Checking multiple truthy value in If statement without logical AND operator

Logical && operator returns true if both or all operands are true:

if (a && b) console.log("Hello");

But today I came across checking for the truthy values in if statement without && logical operator:

if ((a, b)) console.log("Hello");

So I'd like to ask, is this also valid way of checking for the truthy values? Also can you please share your thoughts on how is this working?

Yes, but it doesn't do what you think it does, it only checks `b`. – Teemu Oct 18 '19 at 09:51
So, it checks only the last operand? – Yusufbek Oct 18 '19 at 09:54
[Yep](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Operators/Comma_Operator). – Teemu Oct 18 '19 at 09:55
