compose(arguments) → (function() or Promise)

Compose regular functions or promises generating a final function.

• Compose works from right to left.
• If you compose one single promise the final result will be a promise too.
• You can only compose functions with the same arity.

const sum3 = a => a+3
const mult2 = a => a*2
const sum2Async = a => Promise.resolve(a+2) // Simulate async response

const sumAndMult = compose(sum3,mult2);
sumAndMult(1) // -> (1*2)+3 = 5

const sumAndMultAsync = compose(sum3,mult2,sum2Async);
await sumAndMultAsync(1) // -> ((1+2)*2)+3 = 9

Returns

(function() or Promise) 

function or Promise that execute the all composed ones.

curry(function) → function()

Currify any function allowing the partial application of its arguments

const sum = curry((a,b) = a+b);
const sum3 = sum(3);
sum3(3) // -> 6
sum(3,3) // -> 6
sum(3)(3) // -> 6

Returns

function() 

curried function.

mixCompose(chain, func)

Reducer function used by pipe and compose functions to compose sync and async functions

pipe(arguments) → (function() or Promise)

Compose regular functions or promises generating a final function.

• Compose works from left to right.
• If you compose one single promise the final result will be a promise too.
• You can only compose functions with the same arity.

const sum3 = a => a+3
const mult2 = a => a*2
const sum2Async = a => Promise.resolve(a+2) // Simulate async response

const sumAndMult = pipe(sum3,mult2);
sumAndMult(1) // -> (1+3)*2 = 8

const sumAndMultAsync = pipe(sum3,mult2,sum2Async);
await sumAndMultAsync(1) // -> ((1+3)*2)+2 = 10

Returns

(function() or Promise) 

function or Promise that execute the all composed ones.
