  // - Record name declarations for bindings in the appropriate scope.
  // - Check duplicate argument names, if checkClashes is set.
  //
  // If a complex binding pattern is encountered (e.g., object and array
  // destructuring), the entire pattern is recursively checked.
  //
  // There are three versions of checkLVal*() appropriate for different
  // circumstances:
  //
  // - checkLValSimple() shall be used if the syntactic construct supports
  //   nothing other than identifiers and member expressions. Parenthesized
  //   expressions are also correctly handled. This is generally appropriate for
  //   constructs for which the spec says
  //
  //   > It is a Syntax Error if AssignmentTargetType of [the production] is not
  //   > simple.
  //
  //   It is also appropriate for checking if an identifier is valid and not
  //   defined elsewhere, like import declarations or function/class identifiers.
  //
  //   Examples where this is used include:
  //     a += …;
  //     import a from '…';
  //   where a is the node to be checked.
  //
  // - checkLValPattern() shall be used if the syntactic construct supports
  //   anything checkLValSimple() supports, as well as object and array
  //   destructuring patterns. This is generally appropriate for constructs for
  //   which the spec says
  //
  //   > It is a Syntax Error if [the production] is neither an ObjectLiteral nor
  //   > an ArrayLiteral and AssignmentTargetType of [the production] is not
  //   > simple.
  //
  //   Examples where this is used include:
  //     (a = …);
  //     const a = …;
  //     try { … } catch (a) { … }
  //   where a is the node to be checked.
  //
  // - checkLValInnerPattern() shall be used if the syntactic construct supports
  //   anything checkLValPattern() supports, as well as default assignment
  //   patterns, rest elements, and other constructs that may appear within an
  //   object or array destructuring pattern.
  //
  //   As a special case, function parameters also use checkLValInnerPattern(),
  //   as they also support defaults and rest constructs.
  //
  // These functions deliberately support both assignment and binding constructs,
  // as the logic for both is exceedingly similar. If the node is the target of
  // an assignment, then bindingType should be set to BIND_NONE. Otherwise, it
  // should be set to the appropriate BIND_* constant, like BIND_VAR or
  // BIND_LEXICAL.
  //
  // If the function is called with a non-BIND_NONE bindingType, then
  // additionally a checkClashes object may be specified to allow checking for
  // duplicate argument names. checkClashes is ignored if the provided construct
  // is an assignment (i.e., bindingType is BIND_NONE).

/**
 * Transform a hast tree (with embedded MDX nodes) into an estree.
 *
 * ##### Notes
 *
 * ###### Comments
 *
 * Comments are attached to the tree in their neighbouring nodes (`recast`,
 * `babel` style) and also added as a `comments` array on the program node
 * (`espree` style).
 * You may have to do `program.comments = undefined` for certain compilers.
 *
 * ###### Frameworks
 *
 * There are differences between what JSX frameworks accept, such as whether they
 * accept `class` or `className`, or `background-color` or `backgroundColor`.
 *
 * For JSX components written in MDX, the author has to be aware of this
 * difference and write code accordingly.
 * For hast elements transformed by this project, this will be handled through
 * options.
 *
 * | Framework | `elementAttributeNameCase` | `stylePropertyNameCase` |
 * | --------- | -------------------------- | ----------------------- |
 * | Preact    | `'html'`                   | `'dom'`                 |
 * | React     | `'react'`                  | `'dom'`                 |
 * | Solid     | `'html'`                   | `'css'`                 |
 * | Vue       | `'html'`                   | `'dom'`                 |
 *
 * @param {HastNodes} tree
 *   hast tree.
 * @param {Options | null | undefined} [options]
 *   Configuration (optional).
 * @returns {Program}
 *   estree program node.
 *
 *   The program’s last child in `body` is most likely an `ExpressionStatement`,
 *   whose expression is a `JSXFragment` or a `JSXElement`.
 *
 *   Typically, there is only one node in `body`, however, this utility also
 *   supports embedded MDX nodes in the HTML (when `mdast-util-mdx` is used
 *   with mdast to parse markdown before passing its nodes through to hast).
 *   When MDX ESM import/exports are used, those nodes are added before the
 *   fragment or element in body.
 *
 *   There aren’t many great estree serializers out there that support JSX.
 *   To do that, you can use `estree-util-to-js`.
 *   Or, use `estree-util-build-jsx` to turn JSX into function calls, and then
 *   serialize with whatever (`astring`, `escodegen`).

// expressions and divisions. It is set on all token types that can
// be followed by an expression (thus, a slash after them would be a
// regular expression).

// `yield` expression. It is set on all token types that either can
// directly start an expression (like a quotation mark) or can
// continue an expression (like the body of a string).

//
// - Check that none of the bound/assigned-to identifiers are reserved words.
// - Record name declarations for bindings in the appropriate scope.
// - Check duplicate argument names, if checkClashes is set.
//
// If a complex binding pattern is encountered (e.g., object and array
// destructuring), the entire pattern is recursively checked.
//
// There are three versions of checkLVal*() appropriate for different
// circumstances:
//
// - checkLValSimple() shall be used if the syntactic construct supports
//   nothing other than identifiers and member expressions. Parenthesized
//   expressions are also correctly handled. This is generally appropriate for
//   constructs for which the spec says
//
//   > It is a Syntax Error if AssignmentTargetType of [the production] is not
//   > simple.
//
//   It is also appropriate for checking if an identifier is valid and not
//   defined elsewhere, like import declarations or function/class identifiers.
//
//   Examples where this is used include:
//     a += …;
//     import a from '…';
//   where a is the node to be checked.
//
// - checkLValPattern() shall be used if the syntactic construct supports
//   anything checkLValSimple() supports, as well as object and array
//   destructuring patterns. This is generally appropriate for constructs for
//   which the spec says
//
//   > It is a Syntax Error if [the production] is neither an ObjectLiteral nor
//   > an ArrayLiteral and AssignmentTargetType of [the production] is not
//   > simple.
//
//   Examples where this is used include:
//     (a = …);
//     const a = …;
//     try { … } catch (a) { … }
//   where a is the node to be checked.
//
// - checkLValInnerPattern() shall be used if the syntactic construct supports
//   anything checkLValPattern() supports, as well as default assignment
//   patterns, rest elements, and other constructs that may appear within an
//   object or array destructuring pattern.
//
//   As a special case, function parameters also use checkLValInnerPattern(),
//   as they also support defaults and rest constructs.
//
// These functions deliberately support both assignment and binding constructs,
// as the logic for both is exceedingly similar. If the node is the target of
// an assignment, then bindingType should be set to BIND_NONE. Otherwise, it
// should be set to the appropriate BIND_* constant, like BIND_VAR or
// BIND_LEXICAL.
//
// If the function is called with a non-BIND_NONE bindingType, then
// additionally a checkClashes object may be specified to allow checking for
// duplicate argument names. checkClashes is ignored if the provided construct
// is an assignment (i.e., bindingType is BIND_NONE).

/**
 * Some of the internal operations of micromark do lots of editing
 * operations on very large arrays. This runs into problems with two
 * properties of most circa-2020 JavaScript interpreters:
 *
 *  - Array-length modifications at the high end of an array (push/pop) are
 *    expected to be common and are implemented in (amortized) time
 *    proportional to the number of elements added or removed, whereas
 *    other operations (shift/unshift and splice) are much less efficient.
 *  - Function arguments are passed on the stack, so adding tens of thousands
 *    of elements to an array with `arr.push(...newElements)` will frequently
 *    cause stack overflows. (see <https://stackoverflow.com/questions/22123769/rangeerror-maximum-call-stack-size-exceeded-why>)
 *
 * SpliceBuffers are an implementation of gap buffers, which are a
 * generalization of the "queue made of two stacks" idea. The splice buffer
 * maintains a cursor, and moving the cursor has cost proportional to the
 * distance the cursor moves, but inserting, deleting, or splicing in
 * new information at the cursor is as efficient as the push/pop operation.
 * This allows for an efficient sequence of splices (or pushes, pops, shifts,
 * or unshifts) as long such edits happen at the same part of the array or
 * generally sweep through the array from the beginning to the end.
 *
 * The interface for splice buffers also supports large numbers of inputs by
 * passing a single array argument rather passing multiple arguments on the
 * function call stack.

 *   Whether to persist raw HTML in markdown in the hast tree (default:
 *   `false`).
 * @property {string | null | undefined} [clobberPrefix='user-content-']
 *   Prefix to use before the `id` property on footnotes to prevent them from
 *   *clobbering* (default: `'user-content-'`).
 *
 *   Pass `''` for trusted markdown and when you are careful with
 *   polyfilling.
 *   You could pass a different prefix.
 *
 *   DOM clobbering is this:

 *      (referenceIndex + 1) +
 *      (rereferenceIndex > 1 ? '-' + rereferenceIndex : '')
 *    )
 *   }
 *   ```
 *
 *   Change it when the markdown is not in English.
 *
 *   This label is used in the `ariaLabel` property on each backreference
 *   (the `↩` links).
 *   It affects users of assistive technology.
 * @property {string | null | undefined} [footnoteLabel='Footnotes']
 *   Textual label to use for the footnotes section (default: `'Footnotes'`).
 *
 *   Change it when the markdown is not in English.
 *
 *   This label is typically hidden visually (assuming a `sr-only` CSS class
 *   is defined that does that) and so affects screen readers only.
 *   If you do have such a class, but want to show this section to everyone,
 *   pass different properties with the `footnoteLabelProperties` option.
 * @property {HastProperties | null | undefined} [footnoteLabelProperties={className: ['sr-only']}]
 *   Properties to use on the footnote label (default: `{className:
 *   ['sr-only']}`).
 *
 *   Change it to show the label and add other properties.
 *
 *   This label is typically hidden visually (assuming an `sr-only` CSS class
 *   is defined that does that) and so affects screen readers only.
 *   If you do have such a class, but want to show this section to everyone,
 *   pass an empty string.
 *   You can also add different properties.
 *
 *   > **Note**: `id: 'footnote-label'` is always added, because footnote
 *   > calls use it with `aria-describedby` to provide an accessible label.

 *
 *   Change it to match your document structure.
 *

 * Most utilities ignore `raw` nodes but two notable ones don’t:
 *
 * *   `hast-util-to-html` also has an option `allowDangerousHtml` which will
 *     output the raw HTML.
 *     This is typically discouraged as noted by the option name but is useful
 *     if you completely trust authors
 * *   `hast-util-raw` can handle the raw embedded HTML strings by parsing them
 *     into standard hast nodes (`element`, `text`, etc).
 *     This is a heavy task as it needs a full HTML parser, but it is the only
 *     way to support untrusted content
 *
 * ###### Footnotes
 *
 * Many options supported here relate to footnotes.
 * Footnotes are not specified by CommonMark, which we follow by default.
 * They are supported by GitHub, so footnotes can be enabled in markdown with
 * `mdast-util-gfm`.
 *
 * The options `footnoteBackLabel` and `footnoteLabel` define natural language
 * that explains footnotes, which is hidden for sighted users but shown to
 * assistive technology.
 * When your page is not in English, you must define translated values.
 *
 * Back references use ARIA attributes, but the section label itself uses a
 * heading that is hidden with an `sr-only` class.
 * To show it to sighted users, define different attributes in
 * `footnoteLabelProperties`.
 *
 * ###### Clobbering
 *
 * Footnotes introduces a problem, as it links footnote calls to footnote
 * definitions on the page through `id` attributes generated from user content,
 * which results in DOM clobbering.
 *
 * DOM clobbering is this:
 *
 * ```html
 * <p id=x></p>
 * <script>alert(x) // `x` now refers to the DOM `p#x` element</script>
 * ```
 *
 * Elements by their ID are made available by browsers on the `window` object,
 * which is a security risk.
 * Using a prefix solves this problem.
 *
 * More information on how to handle clobbering and the prefix is explained in
 * Example: headings (DOM clobbering) in `rehype-sanitize`.
 *
 * ###### Unknown nodes
 *
 * Unknown nodes are nodes with a type that isn’t in `handlers` or `passThrough`.
 * The default behavior for unknown nodes is:
 *
 * *   when the node has a `value` (and doesn’t have `data.hName`,
 *     `data.hProperties`, or `data.hChildren`, see later), create a hast `text`
 *     node
 * *   otherwise, create a `<div>` element (which could be changed with
 *     `data.hName`), with its children mapped from mdast to hast as well
 *
 * This behavior can be changed by passing an `unknownHandler`.
 *
 * @param {MdastNodes} tree
 *   mdast tree.
 * @param {Options | null | undefined} [options]
 *   Configuration (optional).
 * @returns {HastNodes}
 *   hast tree.

 *   Transformers handle syntax trees and files.

 *   Whether to keep JSX (default: `false`);
 *   the default is to compile JSX away so that the resulting file is
 *   immediately runnable.
 * @property {string | null | undefined} [jsxImportSource='react']
 *   Place to import automatic JSX runtimes from (default: `'react'`);

 *   it can be used to inject components into the compiled code;
 *   the module must export and identifier `useMDXComponents` which is called
 *   without arguments to get an object of components (`MDXComponents` from
 *   `mdx/types.js`).
