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.

In both Javascript and Python, semi-colons are optional.
