关于WebStorm 占内存的问题，也是有解决方案的。在不需要索引的文件夹上，右键 Mark directory as 选择Exclude，就不会对该文件夹进行索引。 自己测试，只要取消不必要的文件夹索引，比如node_modules,bower_components 这些，真的可以减少很多内存的占用，我使用的情况基本都是2g左右内存的占用（虽然不能和vscode比）。 VSCode 轻量级确实让人垂涎，但是js没有跳转，还怎么用。

利用 indexOf 不需要遍历数组 function moveZero(arr){ let zeroCount=0; let findIndex=0; var index; while(index=arr.indexOf(0, findIndex), index!==-1){ arr.splice(index, 1); zeroCount++; } let zeroArr = Array.from({length:zeroCount}).fill(0); return arr.concat(zeroArr); } let arr=[0,1,0,3,12]; moveZero(arr)
