How to Reduce Functions in Javascript

Run a list of functions and get a list of results:

Hi, I'm a new programmer!

I've been studying for a few months and would like to share this piece of code that came to mind when I studied about the Reduce() function.

I know it's something simple, but it could be useful for many people to extend it, comment on it and improve it.

// Run with Node 11 or higher // DATA-COLLECTING FUNCTIONS const func1 = () => { return { user: 'Diego Perdomo' } } const func2 = () => { return { skills: ['Js', 'React', 'Node', 'Sql'] } } const func3 = () => { return { webs: ['dpercode.com', 'dev.to/diegoper'] } } const func4 = () => { return { articles: ['My Article 1', 'My Article 2'] } } // CREATE ARRAY OF FUNCTIONS const myFunctions = [func1, func2, func3, func4] // REDUCE THE FUNCTIONS const funcReducer = myFunctions.reduce((funcAccumulator, nextFunc) => { let arrayFunc = []; funcAccumulator === undefined ? arrayFunc.push(nextFunc()) : arrayFunc.push(funcAccumulator, nextFunc()) return arrayFunc.flat(); }, undefined) // RESULTS console.log(funcReducer)

// RESULT
[
  { user: 'Diego Perdomo' },
  { skills: [ 'Js', 'React', 'Node', 'Sql' ] },
  { webs: [ 'dpercode.com', 'dev.to/diegoper' ] },
  { articles: [ 'My Article 1', 'My Article 2' ] }
]

Hey Diegoper. That's an interesting approach. However, I think that a map would be more appropriate in this case:

const result = myFunctions.map(func => func())

Hahaha it's good... Thanks
