JavaScript; parsing an IF statement with OR clauses

Question

My question is quite simple, if I declare an IF statement with a series of OR clauses will JavaScript read all of the ORs or stop at the first one that is satisfied?

Thanks in advance.

Answer 1

Stops at the first one. It's called short-circuiting

Answer 2

It should only process upto the first OR that returns true:

if (a || b || c) { 

}

If a is false, b is true and c is true, it will process upto b.
