Question

Hi I’m just going over some basic javascript and I came across this piece of code

if('3'!=3)
{
   document.write("Hello");
}

This writes hello to the screen, however when I change it to:

if('3'==3)
{
   document.write("Hello");
}

This also writes Hello to the screen

Does anyone know any reason for this? I read that javascript converts a string to a number in a comparison I just dont understand the different behavior when I change the condition

Thanks !!

If you want to do a strict comparison use the === operator or !==
