How to convert arraylist to string in Javascript?

Question

I just want to convert arraylist to string in Javascript. I have this code.

var digitStack = [];
digitStack.push(1);
digitStack.push(2);
digitStack.push(3);

and I want to make "123". Any good ideas do you have?

You can use the Array.join() with an empty string as the separator

var digitStack = [];
digitStack.push(1);
digitStack.push(2);
digitStack.push(3);
var string = digitStack.join('');

snippet.log(string)

Just use Array.join() :

var digitStack = [];
digitStack.push(1);
digitStack.push(2);
digitStack.push(3);

var digitStr = digitStack.join('');

console.log(digitStr); // gives you a string.

User Arrayname.join();

var digitStack = [];
digitStack.push(1);
digitStack.push(2);
digitStack.push(3);

var digitStr = digitStack.join(''); //predefined function

document.write(digitStr); // just to verify the string, it has to be removed later
