JavaScript one-line compose (ES6)
const compose = (...fns) => fns.reduce((f, g) => (...args) => f(g(...args)))
// Usage : compose functions right to left
// compose(minus8, add10, multiply10)(4) === 42
//
// The resulting function can accept as many arguments as the first function does
// compose(add2, multiply)(4, 10) === 42

Github README anchor links

To create anchor links that jump down to different sections of a README (as in an interactive table of contents), first create a heading:
#Real Cool Heading

The anchor link for that heading is the lowercase heading name with dashes where there are spaces. You can always get the anchor name by visiting the README on Github.com and clicking on the anchor that appears when you hover to the left of the heading. Copy everything starting at the #:
#real-cool-heading

Wherever you want to link to your Real Cool Heading section, put your desired text in brackets, followed by the anchor link in parentheses:
[Go to Real Cool Heading section](#real-cool-heading)

A set of pure ES2015 functions aimed to make functional JavaScript more idiomatic.
