I have a variable
var number = 1;
I'm then trying to add a 2 onto a number but not add them together like this.
1 + 2 = 2
but instead I want, to join 2 onto the number so i would get
12
1

You can use += and add 2 as string then again convert it to number
var number = 1;
number += '2';
console.log(Number(number));
Use parseInt() to convert the value into integer.

Use this:
var number = 1;
var z = parseInt(number) + '2';
console.log(z);

One way is to add an empty string between the numbers like so:
var number = 1;
var result = number + "" + 2;
alert(result);
Another way it to cast the number to a string using toString()
var number = 1;
var result = number.toString() + 2;
alert(result);
You can use the shorthand
var number = 1;
number = +(number + '' + 2);
console.log(number)
