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.

That's terrifying, especially in JS where no type system will fuck you up for returning nothing when you should've returned a boolean.
