/**
 * Creates a debounced function that delays invoking `func` until after `wait`
 * milliseconds have elapsed since the last time the debounced function was
 * invoked, or until the next browser frame is drawn. 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 the next tick, similar to `setTimeout` with a timeout of `0`.
 *
 * If `wait` is omitted in an environment with `requestAnimationFrame`, `func`
 * invocation will be deferred until the next frame is drawn (typically about
 * 16ms).
 *
 * See [David Corbacho's article](https://css-tricks.com/debouncing-throttling-explained-examples/)
 * for details over the differences between `debounce` and `throttle`.
 *
 * @since 0.1.0
 * @category Function
 * @param {Function} func The function to debounce.
 * @param {number} [wait=0]
 *  The number of milliseconds to delay; if omitted, `requestAnimationFrame` is
 *  used (if available).
 * @param {Object} [options={}] The options object.
 * @param {boolean} [options.leading=false]
 *  Specify invoking on the leading edge of the timeout.
 * @param {number} [options.maxWait]
 *  The maximum time `func` is allowed to be delayed before it's invoked.
 * @param {boolean} [options.trailing=true]
 *  Specify invoking on the trailing edge of the timeout.
 * @returns {Function} Returns the new debounced function.
 * @example
 *
 * // Avoid costly calculations while the window size is in flux.
 * jQuery(window).on('resize', debounce(calculateLayout, 150))
 *
 * // Invoke `sendMail` when clicked, debouncing subsequent calls.
 * jQuery(element).on('click', debounce(sendMail, 300, {
 *   'leading': true,
 *   'trailing': false
 * }))
 *
 * // Ensure `batchLog` is invoked once after 1 second of debounced calls.
 * const debounced = debounce(batchLog, 250, { 'maxWait': 1000 })

/**
 * Creates a throttled function that only invokes `func` at most once per
 * every `wait` milliseconds (or once per browser frame). The throttled 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
 * throttled function. Subsequent calls to the throttled 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 throttled function
 * is invoked more than once during the `wait` timeout.
 *
 * If `wait` is `0` and `leading` is `false`, `func` invocation is deferred
 * until the next tick, similar to `setTimeout` with a timeout of `0`.
 *
 * If `wait` is omitted in an environment with `requestAnimationFrame`, `func`
 * invocation will be deferred until the next frame is drawn (typically about
 * 16ms).
 *
 * See [David Corbacho's article](https://css-tricks.com/debouncing-throttling-explained-examples/)
 * for details over the differences between `throttle` and `debounce`.
 *
 * @since 0.1.0
 * @category Function
 * @param {Function} func The function to throttle.
 * @param {number} [wait=0]
