  2571. * Creates a `lodash` object which wraps `value` to enable implicit method
  2572. * chain sequences. Methods that operate on and return arrays, collections,
  2573. * and functions can be chained together. Methods that retrieve a single value
  2574. * or may return a primitive value will automatically end the chain sequence
  2575. * and return the unwrapped value. Otherwise, the value must be unwrapped
  2576. * with `_#value`.
  2577. *
  2578. * Explicit chain sequences, which must be unwrapped with `_#value`, may be
  2579. * enabled using `_.chain`.
  2580. *
  2581. * The execution of chained methods is lazy, that is, it's deferred until
  2582. * `_#value` is implicitly or explicitly called.
  2583. *
  2584. * Lazy evaluation allows several methods to support shortcut fusion.
  2585. * Shortcut fusion is an optimization to merge iteratee calls; this avoids
  2586. * the creation of intermediate arrays and can greatly reduce the number of
  2587. * iteratee executions. Sections of a chain sequence qualify for shortcut
  2588. * fusion if the section is applied to an array and iteratees accept only
  2589. * one argument. The heuristic for whether a section qualifies for shortcut
  2590. * fusion is subject to change.
  2591. *
  2592. * Chaining is supported in custom builds as long as the `_#value` method is
  2593. * directly or indirectly included in the build.
  2594. *
  2595. * In addition to lodash methods, wrappers have `Array` and `String` methods.

  2605. * `findLast`, `head`, `initial`, `last`, `map`, `reject`, `reverse`, `slice`,
