- How to merge two arrays in JavaScript and de-duplicate items 57 answers
- 如何将两个数组合并到JavaScript和去重复的项目57中?
I'm trying to combine 2 arrays in javascript into one.
我试着把两个数组结合成一个。
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"
这是一个简单的例子，我希望能够合并它们这样当第二行读取时数组中的第4个元素将返回d
How would i do this?
我该怎么做呢?
