如何将 _.debounce 应用到我的 discord 机器人？

Question

我在为此消息添加去抖动时遇到问题。我希望机器人首先像它一样立即发送消息，但在再次发送之前暂停超过 7 秒。我不确定如何或在何处应用去抖动。

bot.on("typingStart", (channel , user) => {

    if (channel.id === Join2_channel) {
    channel.send('Type !join');
    
});

你可以下划线的 _.debounce:

Creates and returns a new debounced version of the passed function which will postpone its execution until after wait milliseconds have elapsed since the last time it was invoked. Useful for implementing behavior that should only happen after the input has stopped arriving. For example: rendering a preview of a Markdown comment, recalculating a layout after the window has stopped being resized, and so on.
At the end of the wait interval, the function will be called with the arguments that were passed most recently to the debounced function.

Pass true for the immediate argument to cause debounce to trigger the function on the leading instead of the trailing edge of the wait interval. Useful in circumstances like preventing accidental double-clicks on a "submit" button from firing a second time.

bot.on("typingStart", _.debounce((channel , user) => {
    
}, 7000, true));

你也可以直接复制函数

// When a sequence of calls of the returned function ends, the argument
// function is triggered. The end of a sequence is defined by the `wait`
// parameter. If `immediate` is passed, the argument function will be
// triggered at the beginning of the sequence instead of at the end.
function debounce(func, wait, immediate) {
  var timeout, result;

  var later = function(context, args) {
    timeout = null;
    if (args) result = func.apply(context, args);
  };

  var debounced = restArguments(function(args) {
    if (timeout) clearTimeout(timeout);
    if (immediate) {
      var callNow = !timeout;
      timeout = setTimeout(later, wait);
      if (callNow) result = func.apply(this, args);
    } else {
      timeout = delay(later, wait, this, args);
    }

    return result;
  });

  debounced.cancel = function() {
    clearTimeout(timeout);
    timeout = null;
  };

  return debounced;
}
// Some functions take a variable number of arguments, or a few expected
// arguments at the beginning and then a variable number of values to operate
// on. This helper accumulates all remaining arguments past the function’s
// argument length (or an explicit `startIndex`), into an array that becomes
// the last argument. Similar to ES6’s "rest parameter".
function restArguments(func, startIndex) {
  startIndex = startIndex == null ? func.length - 1 : +startIndex;
  return function() {
    var length = Math.max(arguments.length - startIndex, 0),
        rest = Array(length),
        index = 0;
    for (; index < length; index++) {
      rest[index] = arguments[index + startIndex];
    }
    switch (startIndex) {
      case 0: return func.call(this, rest);
      case 1: return func.call(this, arguments[0], rest);
      case 2: return func.call(this, arguments[0], arguments[1], rest);
    }
    var args = Array(startIndex + 1);
    for (index = 0; index < startIndex; index++) {
      args[index] = arguments[index];
    }
    args[startIndex] = rest;
    return func.apply(this, args);
  };
}
bot.on("typingStart", debounce((channel, user) => {

}, 7000, true));
