I would like to create new object with value as key in javascript.
I have a obj arrobj, how to create a object having key and value same
function createobj(arrobj){
var newobj = Object.assign({}, ...arrobj.map(e=>Object.values(e.fields)));
return newobj
}
var arrobj = [{
fields: {
service: "finance",
country: "SG"
}
}]
Expected Output
var newobj = {
finance: "finance",
SG: "SG"
}
You can get the values, and then reduce them to a single object with the values as keys:
function createobj(arrobj) {
return arrobj
.flatMap((e) => Object.values(e.fields))
.reduce((p, c) => ((p = { ...p, [c]: c }), p), {});
}
var arrobj = [
{
fields: {
service: "finance",
country: "SG",
},
},
];
console.log(createobj(arrobj));
values variable in any parent scope... but yes, it can be better to just chain the reducevalues function :)I've changed your mapping function, so the object values get accumulated to one opject that is returned then:
function createobj(arrobj){
var newobj = Object.assign({}, ...arrobj.map(e => {
var acc = {};
for (let value of Object.values(e.fields)) {
acc[value] = value;
}
return acc;
}));
return newobj
}
// Test 1
var arrobj = [{
fields: {
service: "finance",
country: "SG"
}
}]
console.log("Test 1:", createobj(arrobj));
// Test 2
var arrobj2 = [{
fields: {
service: "finance",
country: "SG"
}
}, {
fields: {
service: "finance2",
country: "SG2"
}
}]
console.log("Test 2:", createobj(arrobj2));This will give you the output you are looking for:
function createobj(arrobj: any): any {
var newObject = {};
Object.values(arrobj[0].fields).forEach(v => {
newObject[v] = v;
});
return newObject;
}
var arrobj = [ fields: {- something is not right.
