What does ===! operator in JS mean?

Just checked in the browser console,

5 ===! 5  //false
5 ===! 6  //false
5 ===! 7  //false

What's the meaning of ===! ? Yes, three equal signs and exclamation sign thereafter. Thank you.

Or, 5 ===! 5 is treated as 5 === false ?

• 9 Hmmm... === followed by ! maybe? – Álvaro González Commented Oct 21, 2015 at 16:58
• Nope. Exactly as I've asked. Otherwise I won't ask, as I know ! and the difference between == and ===. Thank you. – Haradzieniec Commented Oct 21, 2015 at 16:59

It's not an operator, it's two of them. It is parsed as 5 === (!5), whitespace is ignored between tokens.
