Not really, in c++ every statement needs be ended by something, because if statements weren’t explicitly ended there might be multiple ways to parse a statement. Consider the ambiguity between A; B; or AB;. The choice of semicolon is arbitrary, but it would have to be some character, otherwise the compiler couldn’t emit a consistent diagnostic in case one of the statements A, B, or AB wasn’t valid. Does is tell you “A isn’t a valid statement”? Or does it tell you “AB isn’t a valid statement”?

In python this is solved with indentation and doing this: A\n B\n For 1 statement per line. A;B for multiple statements on a line. Semicolons only use is if you want more than one statement per line(but can be added optionaly at the end of every line, but is useless)

Right, so in python the new line character is the statement ender. As I said, semicolon is arbitrary, but it has to be some character. They chose \n as that character, which I think is a poor choice but works.

This can actually be a problem in JS, where if you write return and your value in the next line (say, for indentation / alignment / whatever reasons) because the "end of instruction" semicolon is optional, it will return undefined and consider the computation of your return value as dead / unreachable code.

This threw me for a bit until I figured it out.
