I'm familiar with the Google Traceur project (which is considered ready for production use in critical systems) as a transpiler from ECMAScript 6 to ECMAScript 5; unfortunately I still have to support IE 8 which is only compatible up to ECMAScript 3!

I'm curious if there are any projects out there to transpile from ECMAScript 6 to ECMAScript 3 so that I would be able to start utilizing ECMAScript 6 functionality now and then just switch over to that code base once IE8 is finally deprecated.

  • I don't know any, but es5-shim might work for you: https://github.com/es-shims/es5-shim – jgillich Apr 18 '14 at 13:59

  • @kangax, Thanks! Exactly what I was looking. BTW; I use your ES5/ES6 compat charts all the time; keep up the good work. – bigtunacan Apr 18 '14 at 19:58
