I am writing a JavaScript section of code and making huge amounts of silly mistakes in the syntax. But the only way to find what line the error is on is to start commenting out the section of code I just wrote and reload it into the browser to narrow down where my missing ');' is.
How do you "compile" a JavaScript source to make sure it is syntactically correct so that I can debug it in the browser?

An exception caused by the incorrect use of a pre-defined syntax. Syntax errors are detected while compiling or parsing source code. For example, if you leave off a closing brace ( } ) when defining a JavaScript function, you trigger a syntax error.
Ctrl + Shift + J in firefox, if you don't catch your mistakes until runtime. Of course firebug works better, but this is a quick way.
