I have two arrays of objects:
Array1:
var myArr1 = [];
myArr1["1"]={any:1,some:1};
myArr1["2"]={any:2,some:2};
myArr1["3"]={any:3,some:3};
Array2:
var myArr2 = [];
myArr2["1"]={other:1};
myArr2["2"]={other:2};
And I want them to be merged by their keys into a new Attribute, so the result will be:
[
{any:1,some:1,myNewAttribute:{other:1}},
{any:2,some:2,myNewAttribute:{other:2}},
{any:3,some:3,myNewAttribute:{other:3}}
]
I tried to achieve it with lodash's _.merge() but I failed miserably. _.merge only adds the second array after the first, but does not match their keys / ids.
You could map the second array to a new property and merge later.
With lodash
var data1 = [{ any: 1, some: 1 }, { any: 2, some: 2 }, { any: 3, some: 3 }],
data2 = [{ other: 1 }, { other: 2 }, { other: 3 }];
console.log(_.merge(data1, _.map(data2, x => ({ myNewAttribute: x }))));<script src="https://cdnjs.cloudflare.com/ajax/libs/lodash.js/4.15.0/lodash.min.js"></script>With ES6, without lodash
var data1 = [{ any: 1, some: 1 }, { any: 2, some: 2 }, { any: 3, some: 3 }],
data2 = [{ other: 1 }, { other: 2 }, { other: 3 }];
console.log(data1.map((a, i) => Object.assign({}, a, { myNewAttribute: data2[i] })));Collected from the Internet
