The Almighty " ; "

I'm working learning javaScript and jQuery. The syntax is killing me. when we put write a function as an argument do we separate all expressions and variables? So for instance:

$("imageGallery a").click(function(event){ event.preventDefault(); var href = $(this).attr("href"); console.log("href") $overlay.show(); });

Basically, what I'm asking is, Does the semi-colon separate all working parts of script? Is it safe to assume that whatever is between semi-colons is separate from other semi-colon'ed parts? I'm sorry if I'm not clear in my question. But like I said the syntax is killing me.

A semicolon indicates an end of a line of code. When you indicate a semicolon, that means that the statement is finished. It's akin to putting a period at the end of a sentence.

$('#myID').hide().fadeIn(); <-- the semi colon ends the line.
