- * 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.

- * `findLast`, `head`, `initial`, `last`, `map`, `reject`, `reverse`, `slice`,
- * `tail`, `take`, `takeRight`, `takeRightWhile`, `takeWhile`, and `toArray`
- *
- * The chainable wrapper methods are:
