In this tutorial, we show you three ways to convert an array to a string in JavaScript.

Check out all JavaScript examples at https://www.javaguides.net/p/javascript-tutorial-with-examples.html

1. Using join() method

The join() method converts the array of elements into a string separated by the commas.

Example 1:

const strArry = ['r','a','m', 'e', 's', 'h'];
console.log(strArry.join());

Output:

r,a,m,e,s,h

Example 2:

const arr = ['r','a','m', 'e', 's', 'h', 1,2,3];
console.log(arr.join());

Output:

r,a,m,e,s,h,1,2,3

We can also pass our own separator as an argument to the join() method.

In this below example, we passed - as a separator argument so that string is separated by a minus operator -.

Example:

const arr = ['r','a','m', 'e', 's', 'h', 1,2,3];
console.log(arr.join('-'));

Output:

r-a-m-e-s-h-1-2-3

2. Using toString() method

The toString() method also joins the array and returns the string where the array of elements is separated by the commas.

Example:

const strArry = ['r','a','m', 'e', 's', 'h'];
console.log(strArry.toString());

Output:

r,a,m,e,s,h

If we add an array with an empty string '' it converts the array to a string.

Example:

const strArry = ['r','a','m', 'e', 's', 'h'];

console.log(strArry + '');

Output:

r,a,m,e,s,h
