Semicolon after statement

Question

Shouldn't the semicolon be obligatory also after the whole "if" statement, not only inside it? (after curly braces)

Answer 1

You put it only where code is executable.

example:

alert("hi"); //action

if (a == 1){} //the action isn't performed by the "if", it's performed by the code inside it...

Answer 2

Well... you can do this :

alert(prompt("text"));

(no need for semicolon after prompt because it returns value to alert thus isn't considered as action)

i don't think there are any exceptions, and if you remove it there are 50% chances that the code will malfunction (because some functions are actions only and don't return value)...

Answer 3

Thanks a million! One, ok two more questions: are there any exceptions? Will it change anything if I'd add semicolon after i.e. the statement you mentioned?
