Convert array of objects to plain object using Ramda

Since everybody is using ES6 already (const), there is a nice pure ES6 solution:

const arrayOfObject = [
  {KEY_A: 'asfas'},
  {KEY_B: 'asas'}
];

Object.assign({}, ...arrayOfObject);
//=> {KEY_A: "asfas", KEY_B: "asas"}

Object.assing merges provided objects to the first one, ... is used to expand an array to the list of parameters.

Ramda has a function built-in for this, mergeAll.

const arrayOfObject = [
     {KEY_A: 'asfas'}
    ,{KEY_B: 'asas' }
];

R.mergeAll(arrayOfObject); 
//=> {"KEY_A": "asfas", "KEY_B": "asas"}
