I would like to compare the 3 javascript variable values and they are equal, need to perform a function.
if(vcount === tcount === lcount){
//do something;
}
and (as per this previous answer)
if((vcount == tcount) && (tcount == lcount)){
//do something;
}
But its not working for me.

consider the following code-
1===1===1
As === operator is left-right associative hence the first part that is 1===1 is evaluated first.
1===1 returns true. then there is the following comparison
true===1
Which is definitely false because boolean true is not same as 1 because === considers value as well as datatype.
boolean it will definitely return false if you use === to compare them. Hence you should always use the 2nd syntax to compare any 3 values.

Try with Conditional(Ternary) Operator (?:) which will help. Please refer below example This is one way of alternative solution
<!DOCTYPE html>
<html>
<body>
<button onclick="myFunction()">Try it</button>
<p id="demo"></p>
<script>
function myFunction()
{
document.getElementById("demo").innerHTML= getResult(7,5,5);
}
function getResult(x,y,z){
return x===y?x===z?true:false:false;
}
</script>
</body>
</html>
