Javascript: How to concatenate two or more variables in an array?

Question

I would like to combine two or more variables into the same array index but not do anything to the values, just place them together in the same array index

So

 var myArray[];
 var one= 1;
 var two = 2;
 etc...
 myArray.push("one" + "two") 
 document.write(myArray[0];

Should output 12 or 1 2 but not add them together to show 3.

Just concatenate them together, perhaps with a space in between? — CertainPerformance, May 27 '18 at 19:51
what do you mean by *place them together in the same array index*? — Nina Scholz, May 27 '18 at 19:54
What's the question here? how to convert a number into a string? or even more basic, like what's the difference between the two? Or what's the difference between adding two numbers and concatenating two strings? — Thomas, May 27 '18 at 19:58

Remove double quotes and for converting to string just add a '' between them. This kind of converting is more efficience than String()

var myArray = [];
var one = 1;
var two = 2;
myArray.push(one + '' + two)
document.write(myArray[0]);

You can do this, using String to convert the numbers into strings and then + will perform string concatenation instead of numeric addition.

const myArray = [];
const one = 1;
const two = 2;

myArray.push(String(one) + String(two));
console.log(myArray);
