Can't use double quotes! Always to use double quotes! "Prefer string/template interpolation" in JS Always do string concatenation per another project's standards.
Lots of different frameworks, languages, projects and companies all force different types of ceremony on formatting. "Hey, just let the tooling tell you!" turns in to constant UI distractions telling you that you're 'wrong' degrades (my?) performance. And... the value of most of these formatting things is pretty low, long term. I know that's heresy to some folks, and everyone I talk to sort of agrees, then says "yeah, but I really think standard XYZ is a good thing", but... it's nearly all preference, just like tabs/spaces.
let longVariableName = "hello " + this.name;
magically becomes
const longVariableName = `hello ${this.name}`;
without visually flagging it, just autocorrects as I type?
And... I can just quickly swap settings for different clients? Because one has eslint block any PRs that don't have "prefer template" rules followed but another client doesn't like that style, and don't want that style in their code because it conflicts with existing style.
I strongly suspect a lot of the remainder of the tabs vs spaces reminder is actually about how it either constrains editor / IDE choices OR requires and investment of time to deal with whichever choice someone else made.
"Why do you care, my IDE just handles this" is pretty close to saying "use my IDE," on top of "use my convention."
if(foo) {
or if (foo) {
or if (foo)
{
you end up in pointless arguments. I don't care about this sort of formatting very much (I have my own default style developed over years), but I do care when other people care about it, often to the exclusion of other factors."but we need these tools so that we don't argue about how to format code". Well... you could... just not argue about it in the first place.
You're right that it's not a matter of there being one true style. I agree with Kevlin Henney though that there are certainly wrong ways to format code - https://youtu.be/ZsHMHukIlJY?t=1027
I don't think this is about becoming expert. This is about learning at least very basics in multiple areas so that you are not completely clueless and know issues exist. When you redefine requirements to "2 years active learning worth of knowledge", you moved goalpost quite far.

This is being senior.
You can be exposed to them, but without understanding them, and experiencing both good, bad, and really bad 'solutions' to them, and understand the impact (on the business, on the code, on security, on maintainability, etc)... you just can't really get all that in 2 years.
I know plenty of people who've been 'exposed' to certain type of tech problems, and the solutions they decide on are objectively really bad for any metric other than "stop this error from showing up on the screen right now".

I had someone call me up to 'fix' a problem in a system I'd given then 15 years earlier. It was still running, more or less the same, and... spelunking your own code 15 years later gives you a new perspective on the impact and value of decisions you make. Many of the things people get hung up on (code style, tabs/spaces/etc, particular naming conventions, etc) provide pretty much no value in digging in to old code that no one has touched or thought about in a decade. Correct comments, sample data, repeatable tests hold so much more value, but are harder to get people to commit to following through on.
