/**
|
|
* 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`,
|

|
|
* `keys`, `keysIn`, `map`, `mapKeys`, `mapValues`, `matches`, `matchesProperty`,
|

* `memoize`, `merge`, `mergeWith`, `method`, `methodOf`, `mixin`, `negate`,
|
|
* `nthArg`, `omit`, `omitBy`, `once`, `orderBy`, `over`, `overArgs`,
|
|
