Separating values in javascript

Question

If I want to calculate the value of x, but I want to keep it from being generated directly next to another value.
Like document.write(x);
And document.write(y);
How can it generate as "x y" instead of "xy"?

Answer 1

Put space after x like this x + " "

you can also write like this

document.write(x + " " + y);
