So in JavaScript there’s the assignment

<span style="color:#323232;">=
</span>

and the comparator is

<span style="color:#323232;">==
</span>

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

<span style="color:#323232;">if(false == '0'){
</span><span style="color:#323232;">    //this is true
</span><span style="color:#323232;">}
</span>

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

<span style="color:#323232;">if(false === '0'){
</span><span style="color:#323232;">    //this is false
</span><span style="color:#323232;">}else{
</span><span style="color:#323232;">    //so this will execute instead 
</span><span style="color:#323232;">}
</span>

But this, however, will

<span style="color:#323232;">var someState = false;
</span><span style="color:#323232;"> if(someState === false){
</span><span style="color:#323232;">    //this is true
</span><span style="color:#323232;">}
</span>
