How to concatenate two numbers in javascript?

Question

I\'d like for something like 5 + 6 to return \"56\" instead of 11.

Answer 1

I'd prefer the concat way :

const numVar1 = 5;
const numVar2 = 6;
const value = "".concat(numVar1, numVar2);
// or directly with values
const value2 = "".concat(5, 6);

You can also use an array which can help in some use cases :

const value3 = [5, 6, numVar1].join('');
