JavaScript: How to join / combine two arrays to concatenate into one array?
提问by Diesal11
I'm trying to combine 2 arrays in javascript into one.
我正在尝试将 javascript 中的 2 个数组合并为一个。
var lines = new Array("a","b","c");
lines = new Array("d","e","f");
This is a quick example, i want to be able to combine them so that when the second line is read the 4th element in the array would return "d"
这是一个快速示例，我希望能够将它们组合起来，以便在读取第二行时，数组中的第 4 个元素将返回“d”
How would i do this?
我该怎么做？

var a = ['a','b','c'];
var b = ['d','e','f'];
var c = a.concat(b); //c is now an an array with: ['a','b','c','d','e','f']
console.log( c[3] ); //c[3] will be 'd'
