JS Operator Lookup

This nifty little project lets you type in or select a JavaScript operator, and it tells you about it!

By Joshua Comeau of www.joshwcomeau.com joshwcomeau.com. Joshua built this project because he was sick of forgetting what these blasted operators are called. Often he'll remember the operator's syntax, but not exactly how it works. One can't use search engines to find out more about them, since they ignore "special characters"!
