Conversion method between js array and string_javascript skills

Many friends who are familiar with js have encountered the situation of converting arrays and strings in js. This article will briefly introduce this. The examples are as follows:

1. Convert array to string

You need to concatenate the array elements into a string using a certain character. The sample code is as follows:

var a, b;
a = new Array(0,1,2,3,4);
b = a.join("-");

2. Convert string to array

The implementation method is to cut the string into several strings according to a certain character and return it in the form of an array. The sample code is as follows:

var s = "abc,abcd,aaa";
ss = s.split(",");// 在每个逗号(,)处进行分解。
