Bring data inside object in array along with other attributes [duplicate]

One liner to flatten nested object

How can I access and process nested objects, arrays, or JSON?
(31 answers)
Closed last month.
I have a array as follows:
data = [
{
"data": {
"id":1,
"vol":"0.0"
"details":{
"ABC":"8.30",
"OFG":"13.85",
"SPG":"70.80"
}
}
},
{
"data": {
"id":2,
"vol":"1.0"
"details":{
"ABC":"3.30",
"OFG":"15.85",
"SPG":"70.80"
}
}
}
]
I want to make an arrays from above array such that data inside details object is every element comes outside. So in my final array there will not be details object. I just want to bring all attributes of details object with other object. So my final array will look something like this
data = [
{
"data": {
"id":1,
"vol":"0.0"
"ABC":"8.30",
"OFG":"13.85",
"SPG":"70.80"
}
},
{
"data": {
"id":1,
"vol":"0.0"
"ABC":"8.30",
"OFG":"13.85",
"SPG":"70.80"
}
}
];
How can I do that?

You can use Array#map with object destructuring.
const arr=[{data:{id:1,vol:"0.0",details:{ABC:"8.30",OFG:"13.85",SPG:"70.80"}}},{data:{id:2,vol:"1.0",details:{ABC:"3.30",OFG:"15.85",SPG:"70.80"}}}];
let res = arr.map(({data: {details, ...rest}}) => ({data : {...rest, ...details}}));
console.log(res);

You could make use of the Spread Operator and do something like this:
const builtData = originalData.map(({ data }) => ({
data: {
id: data.id,
vol: data.vol,
...data.details
}
}))

I want to convert JSON array to a single object. PFB the details
Array:
[{ "item-A": "value-1" }, { "item-B": "value-2" }]
Expected Result:
{ "item-A": "value-1", "item-B": "value-2" }
I have tried following options but result is not what I was expecting
let json = { ...array };
json = Object.assign({}, array);
json = array.reduce((json, value, key) => { json[key] = value; return json; }, {});
Result:
{"0":{"item-A":"value-1"},"1":{"item-B":"value-2"}}

You can use Object.assign and spread the array
const arr=[{ "item-A": "value-1" }, { "item-B": "value-2" }];
console.log(Object.assign({},...arr));

You can use reduce like how you did it with more attention like this:
let array = [{ "item-A": "value-1" }, { "item-B": "value-2" }];
let object = array.reduce((prev, curr) => ({ ...prev, ...curr }), {});
console.log(object);

Get value from object in array: js [duplicate]

Find object by id in an array of JavaScript objects
(36 answers)
Closed 2 years ago.
This is what my array looks like:
const items = [
{ uuid: '123-1234-567', amountMoney: '20,02' },
{ uuid: '111-111-111', amountMoney: '44.04' }
]
And I have the uuid key in the variable:
const uuid = '111-111-111';
Now based on this uuid, I would like to extract the value from the amountMoney: 44.04.
How do you write this in a nice way in js?

You can use Array.prototype.find:
items.find(item => item.uuid === uuid) // -> found object

Use Array.prototype.find to find the object if the property uuid of the object matches the value of the variable uuid. Before extracting the value for amountMoney check if the object was found.
Example,
const items = [
{ uuid: '123-1234-567', amountMoney: '20,02' },
{ uuid: '111-111-111', amountMoney: '44.04' }
]
const uuid = '111-111-111';
const foundItem = items.find(item => item.uuid === uuid);
if (foundItem) {
console.log(foundItem.amountMoney)
}

Checking if an array of objects contains value without looping? [duplicate]

How to determine if Javascript array contains an object with an attribute that equals a given value?

Closed 3 years ago.
Right now I have an array that looks like this
const array = [
{
value: 'received',
title: 'Hjá Birgja',
},
{
value: 'pending',
title: 'Yfirstandandi',
},
{
value: 'processing',
title: 'Í vinnslu',
},
]
and I would like this to return true
if(array.includes('processing'){
// do something
}

not exactly what you wanted since i'm not sure if you only wanted to search the value key but here's a solution
if (array.find(i => i.value === 'processing')) {
// do something
}

Map a string array to a json object in JavaScript [duplicate]

Javascript: How to Get Object property using Array of string? [duplicate]

Closed 3 years ago.
I have a config-file:
{
"permission": {
"users": {
"image": {
"data": "example"
}
}
}
}
And an array with a called path like this:
path = ['users', 'image']
How can I get the data?
First try:
config.permission.path[0].path[1];
Second try:
switch (requestedPath[2]) {
case 'users':
switch (requestedPath[3]) {
case 'image':
mydata = config.permission.users["/image"]
}
}
This will work, but is there a better way?

You need a bracket as property accessor for the object, because you take a variable as key.
config.permission[path[0]][path[1]];
For a more dynamic approach, you could reduce the given data with a default object for not fiund properies.
const getV = (object, path) => path.reduce((result, key) => (result || {})[key], object);
var config = { permission: { users: { image: { data: 'example' } } } },
path = ['users', 'image'];
console.log(getV(config.permission, path));
