How to convert a 2d array to a 2d string in javascript

Question

The problem is quite simple. I would like to convert a 2d array to a string and preserve the brackets. How can I do that? The String() method will remove all the brackets, unfortunately.

Example: [[21, 21], [19, -2]] should be converted to "[[21, 21], [19, -2]]"

Do I need to build a for-loop to do that or is there built-in method or something similar I can use?

Thank you

Have you tried JSON.stringify(yourArray)?

Try

let a = [[21, 21], [19, -2]] ;

console.log( JSON.stringify(a) );
