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/) + * for details over the differences between `_.debounce` and `_.throttle`. + * + * @static + * @memberOf _ + * @since 0.1.0 + * @category Function + * @param {Function} func The function to debounce. + * @param {number} [wait=0] The number of milliseconds to delay. + * @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. + * var debounced = _.debounce(batchLog, 250, { 'maxWait': 1000 }); + * var source = new EventSource('/stream'); + * jQuery(source).on('message', debounced); + * + * // Cancel the trailing debounced invocation. + * jQuery(window).on('popstate', debounced.cancel); + */ + function debounce$1(func, wait, options) { + var lastArgs, + lastThis, + maxWait, + result, + timerId, + lastCallTime, + lastInvokeTime = 0, + leading = false, + maxing = false, + trailing = true; + + if (typeof func != 'function') { + throw new TypeError(FUNC_ERROR_TEXT); + } + wait = toNumber(wait) || 0; + if (isObject(options)) { + leading = !!options.leading; + maxing = 'maxWait' in options; + maxWait = maxing ?
