- * Lazy evaluation allows several methods to support shortcut fusion. Shortcut
- * fusion is an optimization that merges iteratees to avoid creating intermediate
- * arrays and reduce the number of iteratee executions.
- *
- * 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`, `reverse`, `shift`, `slice`, `sort`,
- * `splice`, and `unshift`
- *
- * The wrapper `String` methods are:
- * `replace` and `split`
- *
- * The wrapper methods that support shortcut fusion are:
- * `compact`, `drop`, `dropRight`, `dropRightWhile`, `dropWhile`, `filter`,
- * `first`, `initial`, `last`, `map`, `pluck`, `reject`, `rest`, `reverse`,
- * `slice`, `take`, `takeRight`, `takeRightWhile`, `takeWhile`, `toArray`,
- * and `where`
- *
- * The chainable wrapper methods are:
- * `after`, `ary`, `assign`, `at`, `before`, `bind`, `bindAll`, `bindKey`,
- * `callback`, `chain`, `chunk`, `commit`, `compact`, `concat`, `constant`,
- * `countBy`, `create`, `curry`, `debounce`, `defaults`, `defer`, `delay`,
- * `difference`, `drop`, `dropRight`, `dropRightWhile`, `dropWhile`, `fill`,
- * `filter`, `flatten`, `flattenDeep`, `flow`, `flowRight`, `forEach`,
- * `forEachRight`, `forIn`, `forInRight`, `forOwn`, `forOwnRight`, `functions`,
- * `groupBy`, `indexBy`, `initial`, `intersection`, `invert`, `invoke`, `keys`,
- * `keysIn`, `map`, `mapValues`, `matches`, `matchesProperty`, `memoize`, `merge`,
- * `mixin`, `negate`, `noop`, `omit`, `once`, `pairs`, `partial`, `partialRight`,
- * `partition`, `pick`, `plant`, `pluck`, `property`, `propertyOf`, `pull`,
- * `pullAt`, `push`, `range`, `rearg`, `reject`, `remove`, `rest`, `reverse`,

- * `union`, `uniq`, `unshift`, `unzip`, `values`, `valuesIn`, `where`,
- * `without`, `wrap`, `xor`, `zip`, and `zipObject`
- *
- * The wrapper methods that are **not** chainable by default are:
- * `add`, `attempt`, `camelCase`, `capitalize`, `clone`, `cloneDeep`, `deburr`,
- * `endsWith`, `escape`, `escapeRegExp`, `every`, `find`, `findIndex`, `findKey`,
- * `findLast`, `findLastIndex`, `findLastKey`, `findWhere`, `first`, `has`,
- * `identity`, `includes`, `indexOf`, `inRange`, `isArguments`, `isArray`,
- * `isBoolean`, `isDate`, `isElement`, `isEmpty`, `isEqual`, `isError`,
- * `isFinite`,`isFunction`, `isMatch`, `isNative`, `isNaN`, `isNull`, `isNumber`,
- * `isObject`, `isPlainObject`, `isRegExp`, `isString`, `isUndefined`,
