       * 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.

       * Creates a debounced function that delays invoking `func` until after `wait`
       * milliseconds have elapsed since the last time the debounced function was
       * invoked. The debounced function comes with a `cancel` method to cancel
       * 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`.
       *
       * See [David Corbacho's article](https://css-tricks.com/debouncing-throttling-explained-examples/)
