Use operator priority to implement if else

Using operator priority

If (a) {alert ('true')} else {alert ('false ')}


A & (Alert ('true'), 1) | alert ('false ')

Or use the three-object Operator

A? Alert ('true'): Alert ('false ');

I. Use common ternary Operators

If (FOO) bar (); else Baz () ;=> Foo? Bar (): Baz ();
If (! Foo) bar (); else Baz () ;=> Foo? Baz (): bar ();
If (FOO) return bar (); else return Baz () ;=> return Foo? Bar (): Baz ();

2. Use the and (&) and or (|) Operators

If (FOO) bar () ;=> Foo & Bar ();
If (! Foo) bar () ;=> Foo | bar ();
