batiste/Js sugar

Last active Aug 29, 2015

What would you like to do?
A proposition for some simple syntactic sugar that compiles to Javascript
Goal:
1. Not reinventing JavaScript. Minimalistic sugar.
2. Aleviate the verbosness of the language especially with function definition, semicolon, and the var keyword
3. Avoid CoffeScript error http://lucumr.pocoo.org/2011/12/22/implicit-scoping-in-coffeescript/
Features? Implicit return?
Implementation? PEG.js http://pegjs.majda.cz/online
