    /**
     * Creates a `lodash` object which wraps `value` to enable implicit method
     * chain sequences. Methods that operate on and return arrays, collections,
     * and functions can be chained together. Methods that retrieve a single value
     * or may return a primitive value will automatically end the chain sequence
     * and return the unwrapped value. Otherwise, the value must be unwrapped
     * with `_#value`.
     *
     * Explicit chain sequences, which must be unwrapped with `_#value`, may be
     * enabled using `_.chain`.
     *
     * The execution of chained methods is lazy, that is, it's deferred until
     * `_#value` is implicitly or explicitly called.
     *
     * Lazy evaluation allows several methods to support shortcut fusion.
     * Shortcut fusion is an optimization to merge iteratee calls; this avoids
     * the creation of intermediate arrays and can greatly reduce the number of
     * iteratee executions. Sections of a chain sequence qualify for shortcut
     * fusion if the section is applied to an array and iteratees accept only
     * one argument. The heuristic for whether a section qualifies for shortcut
     * fusion is subject to change.
     *
     * Chaining is supported in custom builds as long as the `_#value` method is
     * directly or indirectly included in the build.
     *
     * In addition to lodash methods, wrappers have `Array` and `String` methods.
     *
     * The wrapper `Array` methods are:
     * `concat`, `join`, `pop`, `push`, `shift`, `sort`, `splice`, and `unshift`
     *
     * The wrapper `String` methods are:
     * `replace` and `split`
     *
     * The wrapper methods that support shortcut fusion are:
     * `at`, `compact`, `drop`, `dropRight`, `dropWhile`, `filter`, `find`,
     * `findLast`, `head`, `initial`, `last`, `map`, `reject`, `reverse`, `slice`,
     * `tail`, `take`, `takeRight`, `takeRightWhile`, `takeWhile`, and `toArray`
     *
     * The chainable wrapper methods are:
     * `after`, `ary`, `assign`, `assignIn`, `assignInWith`, `assignWith`, `at`,
     * `before`, `bind`, `bindAll`, `bindKey`, `castArray`, `chain`, `chunk`,
     * `commit`, `compact`, `concat`, `conforms`, `constant`, `countBy`, `create`,
     * `curry`, `debounce`, `defaults`, `defaultsDeep`, `defer`, `delay`,
     * `difference`, `differenceBy`, `differenceWith`, `drop`, `dropRight`,

  /**
   * Sets the desired offset of a token.
   *
   * This uses a line-based offset collapsing behavior to handle tokens on the same line.
   * For example, consider the following two cases:
   *
   * (
   *     [
   *         bar
   *     ]
   * )
   *
   * ([
   *     bar
   * ])
   *
   * Based on the first case, it's clear that the `bar` token needs to have an offset of 1 indent level (4 spaces) from
   * the `[` token, and the `[` token has to have an offset of 1 indent level from the `(` token. Since the `(` token is
   * the first on its line (with an indent of 0 spaces), the `bar` token needs to be offset by 2 indent levels (8 spaces)
   * from the start of its line.
   *
   * However, in the second case `bar` should only be indented by 4 spaces. This is because the offset of 1 indent level
   * between the `(` and the `[` tokens gets "collapsed" because the two tokens are on the same line. As a result, the
   * `(` token is mapped to the `[` token with an offset of 0, and the rule correctly decides that `bar` should be indented
   * by 1 indent level from the start of the line.
   *
   * This is useful because rule listeners can usually just call `setDesiredOffset` for all the tokens in the node,
   * without needing to check which lines those tokens are on.
   *
   * Note that since collapsing only occurs when two tokens are on the same line, there are a few cases where non-intuitive
   * behavior can occur. For example, consider the following cases:
   *
   * foo(
   * ).
   *     bar(
   *         baz
   *     )
   *
   * foo(
   * ).bar(
   *     baz
   * )
   *
   * Based on the first example, it would seem that `bar` should be offset by 1 indent level from `foo`, and `baz`
   * should be offset by 1 indent level from `bar`. However, this is not correct, because it would result in `baz`
   * being indented by 2 indent levels in the second case (since `foo`, `bar`, and `baz` are all on separate lines, no
   * collapsing would occur).
   *
   * Instead, the correct way would be to offset `baz` by 1 level from `bar`, offset `bar` by 1 level from the `)`, and
   * offset the `)` by 0 levels from `foo`. This ensures that the offset between `bar` and the `)` are correctly collapsed
   * in the second case.
   * @param {Token} token The token
   * @param {Token} fromToken The token that `token` should be offset from
   * @param {number} offset The desired indent level
   * @returns {void}

  /**
   * Sets the desired offset of all tokens in a range
   * It's common for node listeners in this file to need to apply the same offset to a large, contiguous range of tokens.
   * Moreover, the offset of any given token is usually updated multiple times (roughly once for each node that contains
   * it). This means that the offset of each token is updated O(AST depth) times.
   * It would not be performant to store and update the offsets for each token independently, because the rule would end
   * up having a time complexity of O(number of tokens * AST depth), which is quite slow for large files.
   *
   * Instead, the offset tree is represented as a collection of contiguous offset ranges in a file. For example, the following
   * list could represent the state of the offset tree at a given point:
   *
   * * Tokens starting in the interval [0, 15) are aligned with the beginning of the file
   * * Tokens starting in the interval [15, 30) are offset by 1 indent level from the `bar` token
   * * Tokens starting in the interval [30, 43) are offset by 1 indent level from the `foo` token
   * * Tokens starting in the interval [43, 820) are offset by 2 indent levels from the `bar` token
   * * Tokens starting in the interval [820, ∞) are offset by 1 indent level from the `baz` token
   *
   * The `setDesiredOffsets` methods inserts ranges like the ones above. The third line above would be inserted by using:
   * `setDesiredOffsets([30, 43], fooToken, 1);`
   * @param {[number, number]} range A [start, end] pair. All tokens with range[0] <= token.start < range[1] will have the offset applied.
   * @param {Token} fromToken The token that this is offset from
   * @param {number} offset The desired indent level
   * @param {boolean} force `true` if this offset should not use the normal collapsing behavior. This should almost always be false.

     * ## A variable is used from a closure within a loop.
     *
     * A `var` declaration within a loop shares the same variable instance
     * across all loop iterations, while a `let` declaration creates a new
     * instance for each iteration. This means if a variable in a loop is
     * referenced by any closure, changing it from `var` to `let` would

     *
     * ## A variable might be used before it is assigned within a loop.
     *
     * Within a loop, a `let` declaration without an initializer will be
     * initialized to null, while a `var` declaration will retain its value
     * from the previous iteration, so it is only safe to change `var` to
     * `let` if we can statically determine that the variable is always
     * assigned a value before its first access in the loop body. To keep
     * the implementation simple, we only convert `var` to `let` within
     * loops when the variable is a loop assignee or the declaration has an
     * initializer.

 * - ForwardTokenCommentCursor ... The cursor which iterates tokens and comments.

 * @fileoverview The factory of `ConfigArray` objects.
 *
 * This class provides methods to create `ConfigArray` instance.
 *
 * - `create(configData, options)`
 *     Create a `ConfigArray` instance from a config data. This is to handle CLI
 *     options except `--config`.
 * - `loadFile(filePath, options)`
 *     Create a `ConfigArray` instance from a config file. This is to handle
 *     `--config` option. If the file was not found, throws the following error:
 *      - If the filename was `*.js`, a `MODULE_NOT_FOUND` error.
 *      - If the filename was `package.json`, an IO error or an
 *        `ESLINT_CONFIG_FIELD_NOT_FOUND` error.
 *      - Otherwise, an IO error such as `ENOENT`.
 * - `loadInDirectory(directoryPath, options)`
 *     Create a `ConfigArray` instance from a config file which is on a given
 *     directory. This tries to load `.eslintrc.*` or `package.json`. If not
 *     found, returns an empty `ConfigArray`.
 * - `loadESLintIgnore(filePath)`
 *     Create a `ConfigArray` instance from a config file that is `.eslintignore`
 *     format. This is to handle `--ignore-path` option.
 * - `loadDefaultESLintIgnore()`
 *     Create a `ConfigArray` instance from `.eslintignore` or `package.json` in
 *     the current working directory.
 *
 * `ConfigArrayFactory` class has the responsibility that loads configuration
 * files, including loading `extends`, `parser`, and `plugins`. The created
 * `ConfigArray` instance has the loaded `extends`, `parser`, and `plugins`.
 *
 * But this class doesn't handle cascading. `CascadingConfigArrayFactory` class
 * handles cascading and hierarchy.

 *      Those keys are the member ID such as `pluginId/memberName`.
 * - `isRoot()`
 *      If `true` then this configuration has `root:true` property.
 * - `extractConfig(filePath)`
 *      Extract the final configuration for a given file. This means merging
 *      every config array element which that `criteria` property matched. The
 *      `filePath` argument must be an absolute path.
 *
 * `ConfigArrayFactory` provides the loading logic of config files.
