Neither Javascript nor Typescript require semicolon, it is entirely a stylistic choice except in very rare circumstances that do not come up in normal code.

Explanation for nerds

The reason is the JS compiler removes whitespace and introduces semicolons only "where necessary".

So writing

function myFn() {
  return true;
}

Is not the same as

function myFn() {
  return 
    true;
}

Because the compiler will see that and make it:

function myFn() { return; true; }

You big ol' nerd. Tee-hee.

Common JavaScript L

[–] Lemminary@lemmy.world 1 points 1 month ago

Not wrong, but funnily enough, it's a linting rule win. I'd go nuts if I didn't have my type checks and my linters. My current L, though, is setting up the projects initially and dealing with the configuration files if I raw dog it, but that's a problem with ESLint configs and the ecosystem as a whole having to deal with those headaches. So in the end, the JS devs got clever and shifted the blame to the tooling. 😅

That's good to know. Don't know how I didn't know this. Been writing JS since 2000. Always just used them I guess. Ecmascripts look funny to me without them

Fair enough, I like it better without but I don't have a strong preference and have no issue adapting to whatever the style of the repo is.

I learned about it researching tools to automatically enforce formatting style and came across StandardJS, which eliminates them by default.

I can see the benefit of matching style when working with others. I only code for myself and never had to worry about conformity for project consistency.

It is good to learn new things.

I'm sure I have some coding habitats that would annoy others.

Consistent styling helps make the actual meaningful changes easier to spot. Probably also useful for your own commit history when working solo in a repo, but most useful in a team, yeah!

Same here. My brain interprets them as one long run-on sentence and throws a parsing error.
