Rio
Functional Programming Language that compiles to Javascript
Generates ES2016 compatible AST. Assumes Ramda.js as a 'standard' library.
| Rio | Javascript | Why? | Notes |
|---|---|---|---|
| m = 1 | const m = 1 | 'const' is the only type in Rio | |
n/a |
var x = 2 | Rio does not allow mutations | |
n/a |
let x = 3 | same as above | |
| f = x -> !x | const f = x => !x | The thin arrow reminds that in Rio there is no access to 'this' | ... as well as to 'arguments' |
| c = f . g . h | const c = f(g(h)) | ||
| p = resolve(1) >>> delay | const p = Promise.resolve(1).then(delay) | requires: import 'promise' |
