I used var last week, and it made me nostalgic.
I feel kinda bad for var. Sometimes I get the feeling we live in a strictly let and const world these days.
Tell me about the last time you declared a variable with var. What music were you listening to? What was the codebase like? Was it the 90s????

In the console all the time.
Haha if I'm in a console, I don't care about binding semantics and so I usually don't use a declarator at all! A simple
x = 42is sufficient, in that context.For me it's just a good habit
So Python.
I'm too π
same here! it feels so freeing. like running through a field
Definitely, same here, though it seems chrome 80 has added the ability to redefine
letvariablesGood to know, is this only in console or has spec chqnged
I think it's just in the console, they also allow
classto be redefined. You can check the release notes if you're interested in learning more: developers.google.com/web/updates/...Wow
The last time I used
varwas the last time I worked in a JavaScript code base in which I was the only contributor: anytime I try to use it in public, I get shot down by humans or an opinionated linter, or both π.Ideally, I would use it more often. It's not a replacement for
letorconst, just like they aren't drop-in replacements forvaror each other. I actually wrote about how I would prefer to use it here:Using JS: var

I think I haven't used it in years, except in DevTools. Though this is no longer needed with Chrome 80, which allows redefining
let.I was listing to Mozart playing live If I recall correctly. Just kidding, I don't remember exactly when I used it last
I have never looked back, not one single time.
I haven't used it in forever. 95% of the time now I use
const. By making a concerted effort to avoid usingletand the mutability it allows (not thatconstis truly immutable), it has made the code I write much, much cleaner and easier to reason about.I don't use this yet π
Include
letandconst. Because, I write like this is run:Every time I risk polluting global scope including,
<script></script>tag.Yesterday. It'll probably be today, too, but it was definitely yesterday.
Today :'( Legacyyyyy code
My last time was some years ago xD i don't even remember the last time i used it.
