@XadillaX 嗯嗯是滴，提前声明了但没提前赋值

玩一玩ES6吧，这算不算bug呢？@XadillaX ``` javascript "use strict"; function a(x,y){ y = function(){x=2;}; return function(){ y(); console.log(x); let x = 3; //use let }.apply(this,arguments); } a(); ``` iojs运行后报错说x没定义过不能执行`console.log(x)`， 但注释掉 `let x = 3`...

玩点小花样吧，ES5来帮忙 ``` function argments2array(){ return [].map.call(arguments,function(item){ return item }); } ``` 或者ES6（不过V8都还不支持from方法） ``` function argments2array(){ return [].from(arguments) } ```

``` javascript String.prototype.render = function(option){ var s = this, reg; Object.keys(option).forEach(function(k){ reg = new RegExp("\\$\\("+k+"\\)","g"); s = s.replace(reg,option[k]) }); return s }; var greeting = 'my name is $(name),age $(age)';...

@think2011 举个栗子？⊙﹏⊙

FYI - The error shows in VS Code:

试过在 popup 输入 `shift+i` 网易云的歌曲id (307093)，但没有任何效果。 参考问题歌曲： spotify：https://open.spotify.com/track/0pltpGgtKj1CWd7MUWzYT3?si=75f32aca682d4c97 网易云：https://music.163.com/#/song?id=307093
