var <varname> = - the classic. let <varname> = - the modern. const <varname> = - the unchanging <varname> = - the 'oops I made this global by not actually using one' window.<varname> = - the 'deliberate' global
At a guess, anyway... Been wracking my brains to back when I started with classic ASP and early JS in the likes of IE 6 and such, and this is all I can remember... but the brain's not what it used to be, so probably wrong :D
How’s it going, I'm a Adam, a Full-Stack Engineer, actively searching for work. I'm all about JavaScript. And Frontend but don't let that fool you - I've also got some serious Backend skills.

For clarification, <varname> = throws an error in 'strict mode' which means you can't use them inside type="module" scripts, as they are in strict mode by default (source: developer.mozilla.org/en-US/docs/W...).
Definitely - and that's one reason using 'strict' is a massively good thing to do :D Or, perhaps better, use TypeScript and benefit from a more deliberate variable declaration syntax.
For further actions, you may consider blocking this person and/or reporting abuse

Very nice, can you guess the bonus and deprecated variable from js 1.8?
Nope :D I never followed the language definition that far back, I have to admit - and Googling the MDN releases isn't very helpful.

crazzy.
It's a shortcut for creating linked lists? I can see why it got deprecated. Looks like it was a mozilla only tooling...
I have no idea, I didn't stick around to find out. 😂
