no-garbage

no-garbage

Tiny performant subset of JavaScript. Combine with standard for best results.

Usage

$ no-garbage

Rules

• all of ES3
• most of ES5 (for now)
• small selection of ES6 (const, fat arrow, template strings)
• nothing from ES7

ES5 added functional extensions to built-in objects (e.g. Array.forEach). If the :: chaining syntax lands in JS, all ES5 built-in methods can be deprecated, as using external functions (e.g. from npm) will be just as convenient, breaking the TC39's monopoly on nice syntax.

E.g. no more odd unreadable nesting:

const reduce = require('reduce')
const root = require('root')
const map = require('map')

const arr = [ 1, 2, 3, 4 ]
const num = root(reduce(map(arr, (n) => n * n * 2), (t, n) => t + n, 0))

Weird multiline not-quite-lisp:

const reduce = require('reduce')
const root = require('root')
const map = require('map')

const arr = [ 1, 2, 3, 4 ]
const num = root(
  reduce(
    map(arr, (n) => n * n * 2),
  (t, n) => t + n, 0)
)

Or inconvenient placeholder names:

const reduce = require('reduce')
const root = require('root')
const map = require('map')

const arr = [ 1, 2, 3, 4 ]
const mapped = map(arr, (n) => n * n * 2))
const reduced = reduce(mapped, (t, n) => t + n, 0)
const num = root(reduced)

But instead we get nice things:

const reduce = require('reduce')
const root = require('root')
const map = require('map')

const num = [ 1, 2, 3, 4 ]
  ::map((n) => n * n * 2)
  ::reduce((t, n) => t + n, 0)
  ::root()

The less stuff we have to name, the better.

Rant

The TC39 seems to dislike JavaScript so they keep adding new semantics to change the core language. A full reboot so to speak. There's some of us that like JavaScript and would like to keep using it, even if engines support more stuff we didn't ask for. Nanoscript is a tiny, performant subset of JavaScript that doesn't deal with weird semantics (mostly). Have at it. Others might hate JS, but you don't have to hate it too.

Installation
