How to Convert a Comma-Separated String into Array
There is a built-in JavaScript method which you can use and convert a comma-separated string into an array.
The split() method splits a string using a specific separator such as comma (,).
Use a comma separator in the first argument of the split method if you want to split it by comma:
Javascript arrays split method
let str = "Rome,Moscow,Paris,Madrid,Prague,Milan";
let arr = str.split(',');
console.log(arr);
Use the limit parameter to split a string into an array and also get the individual name.
Javascript arrays split method
let str = "Rome,Moscow,Paris,Madrid,Prague,Milan";
let arr = str.split(",", 4);
console.log(arr);
// Output: ["Rome", "Moscow", "Paris", "Madrid"]
console.log(arr[0]);// Output: ["Rome"]
If you pass an empty string, each character will be splitted and converted into an array:
Javascript arrays split method
let str = "W3docs.com";
let arr = str.split("");
console.log(arr);
The split() method
The split() method is called to split a string into an array of substrings and to return a new array. The split() method cuts a string into an ordered set of substrings and puts these substrings into an array returning a new array.
