Check for `console.log(window.a);` – Kunal Mukherjee Aug 08 '20 at 17:15

because 021 is not a number (can't start from 0), so use it as string then: `a = '021';` – tarkh Aug 08 '20 at 17:17

1Since the number is started with `0`, it'll be considered as an Octal value. Hence it's returning 17. – Nithish Aug 08 '20 at 17:19

Because with leading zero it's a octal-number so 21 is 2*8+1 = 16.
But when you print it out it's in decimal.
