Return an array as a string JavaScript

I want return an array as a string in my function.
Example: 

return [[1],[1,1],[1,2,1],[1,3,3,1],[1,4,6,4,1]]

should be returned as "[[1],[1,1],[1,2,1],[1,3,3,1],[1,4,6,4,1]]" which is a string. I don't want to use .join() because it removes the [] brackets.

Return your array after JSON.stringify it. like that:

var arr = [[1],[1,1],[1,2,1],[1,3,3,1],[1,4,6,4,1]];
return JSON.stringify(arr);

It will convert the array object into string.

You can use JSON.stringify - it converts JS objects into JSON strings.

console.log(JSON.stringify([[1],[1,1],[1,2,1],[1,3,3,1],[1,4,6,4,1]]));
