javascript - 将 5 个字符串数组合并为一个

Question

如何合并多个(5 个数组合为一个):

var arr1 = ['a','b'];
var arr2 = ['c','d','n'];
var arr3 = ['e','f'];
var arr4 = ['g','h'];
var arr5 = ['o','p','q'];

我尝试这样做，但没有运气:

objCls = arr1 + arr2 + arr3 + arr4 + arr5;
var objectsClass = objCls.split(',');    

Answer 1

var all = [].concat(arr1, arr2, arr3, arr4, arr5)

所有五个输入数组均保持不变。文档:Array::concat .
