Companies using LiveScript
We use LiveScript extensively for our front-end UI, totaling over 12,000 lines of code, converted from JS and Coffee by the inimitable @gkz.
LiveScript is used on both the server and client in all of our new development. We also have a lot of CoffeeScript code. The amount of PHP we have to maintain is dwindling by the day.
All 13000 lines of our frontend server and client are LiveScript, with nary a line of JavaScript to be seen.
