* Creates a `lodash` object which wraps the given value to enable intuitive // 523 | |

* In addition to Lo-Dash methods, wrappers also have the following `Array` methods: // 526 | |
* `concat`, `join`, `pop`, `push`, `reverse`, `shift`, `slice`, `sort`, `splice`, // 527 | |
* and `unshift` // 528 | |
* // 529 | |
* Chaining is supported in custom builds as long as the `value` method is // 530 | |
* implicitly or explicitly included in the build. // 531 | |
* // 532 | |
* The chainable wrapper functions are: // 533 | |
* `after`, `assign`, `bind`, `bindAll`, `bindKey`, `chain`, `compact`, // 534 | |
* `compose`, `concat`, `countBy`, `create`, `createCallback`, `curry`, // 535 | |
* `debounce`, `defaults`, `defer`, `delay`, `difference`, `filter`, `flatten`, // 536 | |
* `forEach`, `forEachRight`, `forIn`, `forInRight`, `forOwn`, `forOwnRight`, // 537 | |
* `functions`, `groupBy`, `indexBy`, `initial`, `intersection`, `invert`, // 538 | |
* `invoke`, `keys`, `map`, `max`, `memoize`, `merge`, `min`, `object`, `omit`, // 539 | |
* `once`, `pairs`, `partial`, `partialRight`, `pick`, `pluck`, `pull`, `push`, // 540 | |
* `range`, `reject`, `remove`, `rest`, `reverse`, `shuffle`, `slice`, `sort`, // 541 | |
* `sortBy`, `splice`, `tap`, `throttle`, `times`, `toArray`, `transform`, // 542 | |
* `union`, `uniq`, `unshift`, `unzip`, `values`, `where`, `without`, `wrap`, // 543 | |
* and `zip` // 544 | |
* // 545 | |
* The non-chainable wrapper functions are: // 546 | |
* `clone`, `cloneDeep`, `contains`, `escape`, `every`, `find`, `findIndex`, // 547 | |
* `findKey`, `findLast`, `findLastIndex`, `findLastKey`, `has`, `identity`, // 548 | |
* `indexOf`, `isArguments`, `isArray`, `isBoolean`, `isDate`, `isElement`, // 549 | |
* `isEmpty`, `isEqual`, `isFinite`, `isFunction`, `isNaN`, `isNull`, `isNumber`, // 550 | |
* `isObject`, `isPlainObject`, `isRegExp`, `isString`, `isUndefined`, `join`, // 551 | |
* `lastIndexOf`, `mixin`, `noConflict`, `parseInt`, `pop`, `random`, `reduce`, // 552 | |
* `reduceRight`, `result`, `shift`, `size`, `some`, `sortedIndex`, `runInContext`, // 553 | |
* `template`, `unescape`, `uniqueId`, and `value` // 554 | |
* // 555 | |
* The wrapper functions `first` and `last` return wrapped values when `n` is // 556 | |
