JS: Array.prototype.toString

By Xah Lee. Date: . Last updated: .

myArray.toString ()

Return a string representation of myArray.

For example, [3,4,5] becomes "3,4,5".

const arr = [3, 4, 5];
console.log (
    arr.toString () === "3,4,5"
); // true

// note: no bracket in result
console.log (
    [3, [1,[2]], 5].toString () === "3,1,2,5"
); // true

// note: no bracket in result, even for nested array
console.log (
    [3, {k:4}].toString () === "3,[object Object]"
); // true
