Converting a comma separated string to an Array in JavaScript

In this tutorial, we are going to learn about how to convert a comma (,) separated string to an array in JavaScript.

Using JavaScript split() method

To convert a comma-separated string to an array we need to use the split() method in JavaScript.

The Split() converts the string into an array of strings, followed by separator argument.

Example:

const letters = 'a,b,c,d';

console.log(letters.split(','));

// ouput -->   ["a", "b", "c", "d"]

In the above code, we passed comma (,) as an argument to the split() method so that its start separating the string at each comma and returns the array.

Limiting the number of splits

We can also limit the number of splits by passing a second argument to the split() method.

This below example returns the first two splits it finds in a string.

const letters = 'a,b,c,d';

console.log(letters.split(',' , 2));

// output --> ["a", "b"]
