repl (read-eval-print-loop)
This repl was built with traceur-compiler,
and CodeMirror2 so you can use ES6 features now!
Control the available ES6 options from the "Options" menu.
By default, the really cool, stable stuff is already enabled--you're welcome.
The "Examples" menu contains sample code I made to either get you started with your own
experiments or let you bask in the glory of my creation.
The "Reset" button (because there should always be a big, red button) clears the repl and repl
history.
