I think ElixirScript has more legs. RedScript was just a project I tinkered with 2 years ago and recently refreshed it post ES6 era and after getting into &#x27;functiona&#x27; programming.<p>RedScript is more like CoffeeScript and ElixirScript is more like Elm&#x2F;ClojureScript IMHO. It has little to no overhead overhead after transpiling however 2.0 will use seamless-immutable (via CommonJS) to help with copying data.<p>Here&#x27;s the 1.0 before&#x2F;after conversions:

It&#x27;s surprising how far it takes you. I&#x27;ve built a small web app with it and it works well. I don&#x27;t trust the compiled output without testing though (due to the RegEx strategy).<p>I haven&#x27;t had to the time to make the changes in the complier but shouldn&#x27;t take more than a few beers and a weekend :)
