Hello, would someone kindly explain why this code doesn't display anything?

Question

var x = 0;

while(x<10){
document.write(x + "<br>");
x+2;
}

Answer 1

You should do increment so you need to write x=x+2 rather then x+2

Ok

Answer 2

It should x+=2 not x+2

Answer 3

learn about operators. assignment, arihmetic, logical relational. what youve written is an arihmetic operator, while you want an assignment operator.
