I have json object like this
[
{
"tag": "search"
},
{
"tag": "test"
},
{
"tag": "css"
},
]
But i want to get this object like this
'search',
'test',
'css',
How do I do this?

You can map over the array and extract the tag property value:
const obj = [ { "tag": "search" }, { "tag": "test" }, { "tag": "css" }, ]
const res = obj.map(e=>e.tag)
console.log(res)

I need to filtered upper array elements to object elements using javascript. Here array value need to object key & value
let filteredObject = Object.create(null);
for(let filter of filtered) {
filteredObject[filter[0]] = Object.create(null);
filteredObject[filter[0]][filter[1]] = filter[2];
}
Object.create(null) may be omitted and replaced with {} if you are certain that a trusted entity is in control of the strings in the filtered array.

I want to convert this:
data: {
"3": {
name: ["Missing data for required field."],
},
"5": {
id: ["Same id exist."],
},
}
into this:
data: [{
key: "name",
message: "Missing data for required field.",
row: 3,
},
{
key: "id",
message: "Same id exist.",
row: 5,
},]
how to achieve this with just es6 syntax
You can do this with Object.entries:
const data = {
"3": {
name: ["Missing data for required field."]
},
"5": {
id: ["Same id exist."]
}
};
Object.entries(data).map(([a, b]) => {
return {
key: Object.keys(b)[0],
message: Object.values(b)[0][0],
row: a
};
});
I've made some assumptions:
There will only be one key in each object
The value of the key will be an array with one string

I have an array of objects like this :
[
{
"event" : {
"teams": "bla bla",
}
},
{
"event" : {
"teams": "bla bla",
}
},
]
How to combine all events that have the same teams value into one array like this:
[
{
"event" : [
{
"teams" : "bla bla"
},
{
"teams": "bla bla"
},
]
}
]
I can only use lodash
This would convert the first object objectArray into the other.
const combinedArray = [{ event: objectArray.map(obj => obj.event) }];
Edit: Grouping by teams
const groupedArray = [];
const teams = new Set(objectArray.map(obj => obj.event.teams).filter(n=>n));
for (const team of teams)
groupedArray.push({ event: objectArray.map(obj=>obj.event).filter(event => event.teams === team)});

for(var key in obj) {
