I had an array
[{0:{title:"test1"}},{1:{message1:"message1"}},{2:{message2:"message2"}}]
I want to get an Object in below format
{title:"test1",message1:"message1",message2:"message2"}
I am trying with below code but no luck
var rv = {};
for (var i = 0; i < messageArray.length; ++i)
if (messageArray[i] !== undefined) rv[i] = messageArray[i];`
It results me
{0: {title:"test1"}, 1: {message1:"message1"},2: {message2:"message2"}}
You can use reduce to summarize the data and Object.assign() to merge new properties into an object.
let arr = [{0:{title:"test1"}},{1:{message1:"message1"}},{2:{message2:"message2"}}];
let result = arr.reduce((c, v, i) => Object.assign(c, v[i]),{});
console.log(result);If the key on your objects are not on sequence, you can use Object.values() to get the values.
let arr = [{0:{title:"test1"}},{1:{message1:"message1"}},{2:{message2:"message2"}}];
let result = arr.reduce((c, v, i) => Object.assign(c, Object.values(v)[0]), {});
console.log(result);You can use .map() and .reduce():
let data = [
{0:{title:"test1"}},
{1:{message1:"message1"}},
{2:{message2:"message2"}}
];
let result = data.map((c, i) => c[i])
.reduce((a, c) => Object.assign(a, c), {});
console.log(result);Docs:
You can combine the items by spreading into Object.assign(). Then get the internal values via Object.values(), and merge them again by spreading into Object.assign():
const data = [{0:{title:"test1"}},{1:{message1:"message1"}},{2:{message2:"message2"}}];
const result = Object.assign(...Object.values(Object.assign({}, ...data)));
console.log(result);You should make your array flat
const rv = [];
for (var i = 0; i < messageArray.length; ++i) {
if (messageArray[i] !== undefined)
rv.push(messageArray[i]);
}
Then can use Array.reduce, it should look like
rv.reduce((result, element) => {
Object.keys(element).forEach((key) => {
result[key] = element[key];
});
return result;
}, {});
You can iterate over each property, and use Object.assign to extend the current object with each property.
var object = {};
var input = [{0:{title:"test1"}},{1:{message1:"message1"}},{2:{message2:"message2"}}];
for (var i = 0; i < input.length; i++) {
object = Object.assign(input[i][i], object);
}
console.log(object);
/*
{
"message2": "message2",
"message1": "message1",
"title": "test1"
}
*/The following code should give desired results without Object.assign :
//Using map() and reduce()
var arr = [{0:{title:"test1"}},{1:{message1:"message1"}},{2:{message2:"message2"}}];
var result = arr.map(function(item,i){
return item[i];
})
.reduce(function(acc,item){
return {...acc,...item}
},{})
console.log(result); // {title: "test1", message1: "message1", message2: "message2"}
Hope this helps!
