Same for

if(a!=123) // before // NOOBS

if(a^123) // after // PRO
Enter fullscreen mode Exit fullscreen mode

a^123 is not very clean IMO. Maybe a better one will be if(a !== 123)

And it's not correct for decimal numbers.

Boolean(122^123) // true
Boolean(123.1^123) // false -> is not correct, should be true 123.1 !== 123
Boolean(123^123) // false
Enter fullscreen mode Exit fullscreen mode

Much better to use the !== operator.
