===

So in JavaScript there’s the assignment

=

and the comparator is

==

Since there’s no types JS will do implicit conversion before comparison when using == in a case like this

if(false == '0'){
    //this is true
}

But with === it doesn’t. It means literally compare these

if(false === '0'){
    //this is false
}else{
    //so this will execute instead 
}

But this, however, will

var someState = false;
 if(someState === false){
    //this is true
}
