Do you really need a semicolon in Javascript / jQuery?

Do you really need a semicolon after each statement? Or is it like Swift, which doesn't require a ";" after a statement

Javascript has specific rules about when and where semi-colons are needed. For the most part, yes, it does require a semi-colon after each statement but there are times when doing so could stop the rest of your code from being read.

I'd suggest you complete the Full-Stack Javascript Course if you aren't doing so now, for a better understanding of these rules.

I hope this helps.

This is a matter of taste according to some. I myself use them for readability. A few places even 'require' using them, https://github.com/airbnb/javascript#semicolons.
