Lets say I have 2 arrays of objects and I want to merge their objects in parallel manner. For example
var array = [{foo: 2} , {boo: 3}] var array2 = [{foo2: 2}, {boo2: 4}] The result will be
var array3 = [{foo:2,foo2:2},{boo:3,boo2:4}] How can I do it in javascript?
You might want to use Array.prototype.map and Object.assign for the merge.
array.map((obj,index) => Object.assign(obj,array2[index])); You can traverse through one array and pick one item and pick the item from the another array and then merge them.
var array = [{foo: 2} , {boo: 3}]; var array2 = [{foo2: 2}, {boo2: 4}]; var _o = array.map(function(obj1, i){ var obj2 = array2[i]; for (var attrname in obj2) { obj1[attrname] = obj2[attrname]; } return obj1; }); // _o is the final array alert(JSON.stringify(_o));You should look a lodash:
var users = { 'data': [{ 'user': 'barney' }, { 'user': 'fred' }] }; var ages = { 'data': [{ 'age': 36 }, { 'age': 40 }] }; _.merge(users, ages); // → { 'data': [{ 'user': 'barney', 'age': 36 }, { 'user': 'fred', 'age': 40 }] }
