Looking for a lightweight code editor? Here are a few that are worth a look.
Brackets is open source and is rather full featured. It integrates with Chrome and updates a running browser window in real time as you make code changes.
ATOM is also open source and is motivated to be “hackable to the core.” It happens to integrate nicely with Node.js, if that’s your thing.
Sublime has been around for a long time, but wants a good chunk of change to buy a license. Many continue using it past the trial period and just click past the scolding “purchase me” message.

Light Table, http://lighttable.com/, looks like an interesting reboot of a programmers code editor. I haven’t spent more than a few minutes with yet. I’d be interested in hearing other people’s opinions.
