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 }] }
