Lodash create an object from a collection

Question

With the following array;

var arr = [
    {"name": "blah"},
    {"version": "v1.0.0"},
    ...
]

I would like to create the following object with lodash;

var obj = {
    "name": "blah",
    "version": "v1.0.0",
    ...
}

P.S. Duplicates don't matter as there won't be any here.

I haven't tried anything, I'm just curious as to what method would be used from lodash or how one might do this? — stackunderflow

Here is a solution using plain JavaScript.

References:

Object.assign can be used to concatenate Objects({}).
Array.prototype.reduce can be used to minimize the Array([]) values.

var arr = [{
  "name": "blah"
}, {
  "version": "v1.0.0"
}];

var obj = arr.reduce(function(o, v) {
  return Object.assign(o, v);
}, {});

console.log(obj);

Why use lodash when you can do it in pure js?

var arr = [
  {
    "name": "blah"
  }, 
  {
    "version": "v1.0.0"
  }
]

var obj = arr.reduce(function(acc, val) {
  var key = Object.keys(val)[0];
  acc[key] = val[key];
  return acc;
}, {})

console.log(obj)

Thank you, I just like lodash for its cleanliness.

Lodash implementation.

var arr = [{
  "name": "name"
}, {
  "version": "v1.0.0"
},{
  "manager": "manager"
}];

var result = _.reduce(arr, function(object, value) {
  return _.assign(object, value);
}, {});

console.log(result);
