Javascript - Ternary Operator with Multiple Statements

Question

Is this valid JavaScript? I saw an example where someone used commas in the ternary operator conditions, and it was marked as an error in my editor, and the example didn\'t

Answer 1

Yes:

a=1;
b=2;

a!==b ? (a=1, b=2) : (a=2, b=1)

console.log(a);     // 1
console.log(b);     // 2

and:

a=1;
b=2;

a===b ? (a=1, b=2) : (a=2, b=1)

console.log(a);     // 2
console.log(b);     // 1

As you can analyze, changing the equality operator reacts correctly to our test if you look at the results.
