+ * 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.

+ * `concat`, `join`, `pop`, `push`, `shift`, `sort`, `splice`, and `unshift`
+ *
+ * The wrapper `String` methods are:

- * 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`,

+ * delayed `func` invocations and a `flush` method to immediately invoke them.
+ * Provide `options` to indicate whether `func` should be invoked on the
+ * leading and/or trailing edge of the `wait` timeout. The `func` is invoked
+ * with the last arguments provided to the debounced function. Subsequent
+ * calls to the debounced function return the result of the last `func`
+ * invocation.
+ *
+ * **Note:** If `leading` and `trailing` options are `true`, `func` is
+ * invoked on the trailing edge of the timeout only if the debounced function
+ * is invoked more than once during the `wait` timeout.
+ *
+ * If `wait` is `0` and `leading` is `false`, `func` invocation is deferred
+ * until to the next tick, similar to `setTimeout` with a timeout of `0`.
