JS分号删除了“未捕获的SyntaxError：意外的标识符”错误，为什么？

Question

My code is this:

message.labels.forEach(/…/) container.data.push(message);

It throws Uncaught SyntaxError: Unexpected identifier When I add a semicolon after the forEach function it doesn't throw it anymore. I only change the semicolon there, I checked it with my git.

Why does it do it? Feels like I'm missing some JS fundamentals here.

Answer 1

The semi-colon ends a statement .

If you leave it out, then your two statements are treated as a single one, it doesn't make any sense and the compiler throw an error.
