Fun Facts

  • LightTable is built with node-webkit (which is another cool project)
  • Raised $316,720 on KickStarter, then Funded on YC 
  • Created with ClosureScript for ClosureScript
  • Vim Bindings
  • Chris Granger, the guy behind Light Table IDE, worked on VS before this
  • Possibly inspired by Bret Victor's Inventing on Principle

Tips and Tricks

  1. Use Ctrl-Space for anything
  2. Use Cmd+Enter (or Ctrl-Enter) for Previews
  3. Cmd+Enter on HTML will launch the browser
  4. Separate css and js files from HTML to enable live coding
  5. Cmd+Enter on Variables/Functions/Block will eval section
  6. Move functions / variable scopes to a top level for hot code replacement / eval to work
  7. Use Tabsets to make your workspace neater
  8. Live coding also works with NodeJS and ipython processes



A large fraction of the flaws in software development are due to programmers not fully understanding all the possible states their code may execute in.
