/**
* throttle 函数节流
* @since 1.0.0
* @example 适用于限制`resize`和`scroll`等函数的调用频率
* @param {Number} delay 0 或者更大的毫秒数。 对于事件回调,大约100或250毫秒(或更高)的延迟是最有用的。
* @param {Boolean} noTrailing 可选,默认为false。
* 如果noTrailing为true,当节流函数被调用,每过`delay`毫秒`callback`也将执行一次。
* 如果noTrailing为false或者未传入,`callback`将在最后一次调用节流函数后再执行一次.
* (延迟`delay`毫秒之后,节流函数没有被调用,内部计数器会复位)
* @param {Function} callback 延迟毫秒后执行的函数。`this`上下文和所有参数都是按原样传递的,
* 执行去节流功能时,调用`callback`。
* @param {Boolean} debounceMode 如果`debounceMode`为true,`clear`在`delay`ms后执行。
* 如果debounceMode是false,`callback`在`delay` ms之后执行。
* @return {Function} 新的节流函数

* debounce 函数防抖

* @example 适用场景:如在线编辑的自动存储防抖。
* @param {Number} delay 0或者更大的毫秒数。 对于事件回调,大约100或250毫秒(或更高)的延迟是最有用的。
* @param {Boolean} atBegin 可选,默认为false。
* 如果`atBegin`为false或未传入,回调函数则在第一次调用return的防抖函数后延迟指定毫秒调用。
* 如果`atBegin`为true,回调函数则在第一次调用return的防抖函数时直接执行
* @param {Function} callback 延迟毫秒后执行的函数。`this`上下文和所有参数都是按原样传递的,
* 执行去抖动功能时,,调用`callback`。
* @return {Function} 新的防抖函数。
