-     * 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 of at least `200` elements
-     * and any 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:

-     *
-     * The wrapper `String` methods are:
-     * `replace` and `split`
-     *
-     * The wrapper methods that support shortcut fusion are:

-     * `findLast`, `head`, `initial`, `last`, `map`, `reject`, `reverse`, `slice`,
-     * `tail`, `take`, `takeRight`, `takeRightWhile`, `takeWhile`, and `toArray`

-     * Creates a throttled function that only invokes `func` at most once per
-     * every `wait` milliseconds. The throttled function comes with a `cancel`
-     * method to cancel delayed `func` invocations and a `flush` method to
-     * immediately invoke them. Provide `options` to indicate whether `func`
-     * should be invoked on the leading and/or trailing edge of the `wait`
-     * timeout. The `func` is invoked with the last arguments provided to the
-     * throttled function. Subsequent calls to the throttled function return the
-     * result of the last `func` invocation.
-     *
-     * **Note:** If `leading` and `trailing` options are `true`, `func` is
-     * invoked on the trailing edge of the timeout only if the throttled function
-     * is invoked more than once during the `wait` timeout.
-     *
-     * If `wait` is `0` and `leading` is `false`, `func` invocation is deferred
-     * until to the next tick, similar to `setTimeout` with a timeout of `0`.
