It mostly means that it's not JavaScript. The postfix `!` is used by TypeScript, for example. – Bergi Dec 07 '20 at 17:07

that's not JS syntax, the author seems to have forgotten that they weren't writing typescript. – Mike 'Pomax' Kamermans Dec 07 '20 at 17:07

@Mike'Pomax'Kamermans The examples on the linked page certainly were *meant* to be typescript even :-) – Bergi Dec 07 '20 at 17:10
