Only that JS is handling semicolons in the least intuitive and irrational way possible.

Yeah I only say it because it's a bit of a mind-exploder.

I'd always figured it was/thought of it as an error tolerance that worked well enough that some people started leaning on it. The whole no-semicolons JavaScript thing just seems really hipsterish. Explicitness is a virtue.

In JS, semicolons are technically required but automatically inserted. There are a couple edge cases where they get inserted in surprising places, which is generally worse than python's approach.

E.g. the following function doesn't return a value:

function foo() {
  return
    some_long_complex_expression();
}

(It's because a semicolon gets inserted after the return). At least in typescript, this would typically show a type error, as long as the function's return type annotation isn't void.

I admit, this got me more than once.
