| * `_#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`, | |
| * `dropRightWhile`, `dropWhile`, `extend`, `extendWith`, `fill`, `filter`, | |
| * `flatMap`, `flatMapDeep`, `flatMapDepth`, `flatten`, `flattenDeep`, | |
| * `flattenDepth`, `flip`, `flow`, `flowRight`, `fromPairs`, `functions`, | |
| * `functionsIn`, `groupBy`, `initial`, `intersection`, `intersectionBy`, | |
| * `intersectionWith`, `invert`, `invertBy`, `invokeMap`, `iteratee`, `keyBy`, | |
| * `keys`, `keysIn`, `map`, `mapKeys`, `mapValues`, `matches`, `matchesProperty`, | |
| * `memoize`, `merge`, `mergeWith`, `method`, `methodOf`, `mixin`, `negate`, | |
| * `nthArg`, `omit`, `omitBy`, `once`, `orderBy`, `over`, `overArgs`, | |
| * `overEvery`, `overSome`, `partial`, `partialRight`, `partition`, `pick`, | |
| * `pickBy`, `plant`, `property`, `propertyOf`, `pull`, `pullAll`, `pullAllBy`, | |
| * `pullAllWith`, `pullAt`, `push`, `range`, `rangeRight`, `rearg`, `reject`, | |
| * `remove`, `rest`, `reverse`, `sampleSize`, `set`, `setWith`, `shuffle`, | |
| * `slice`, `sort`, `sortBy`, `splice`, `spread`, `tail`, `take`, `takeRight`, | |

| * `valuesIn`, `without`, `wrap`, `xor`, `xorBy`, `xorWith`, `zip`, | |
| * `zipObject`, `zipObjectDeep`, and `zipWith` | |

| * `cloneDeep`, `cloneDeepWith`, `cloneWith`, `conformsTo`, `deburr`, | |
