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.
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
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!
Was looking at it and could not figure out why their weren’t any semicolon’s.

Explanation for nerds
The reason is the JS compiler removes whitespace and introduces semicolons only “where necessary”.
So writing
Is not the same as
Because the compiler will see that and make it:
You big ol’ nerd. Tee-hee.
That’s terrifying, especially in JS where no type system will fuck you up for returning nothing when you should’ve returned a boolean.

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

Hmm, a webdev colleague said he’d normally prefer without semicolons, but used them anyways for better compile errors.
Interesting, I’m not aware of any way they would affect compile errors. I’d be curious to know more.
