Script Preparation code:

var _compose = (f, g) => (...args) => f(g(...args))
var compose = (...funcs) => funcs.reduce(_compose)

var _pipe = (f, g) => (...args) => g(f(...args))
var pipe = (...funcs) => funcs.reduce(_pipe)

var pipe2 = (...funcs) => funcs.reduceRight(_compose)

Tests:

Pipe
pipe(x => x + 'b', x => x + 'c')('a')
Pipe2
pipe2(x => x + 'b', x => x + 'c')('a')
Compose
compose(x => x + 'c', x => x + 'b')('a')
