And i need to make from these 2 objects one. Output:

obj3 = [{A:1}, {B:2}, {C:3}...,]

Anybody know how to merge obj and obj2 to one? Thanks!

Answer 1

If you have consitent nameing, you could map with index.

const
 names = [{ name: 'A' }, { name: 'B' }, { name: 'C' }],
 values = [{ value: 1 }, { value: 2 }, { value: 3 }],
 result = names.map(({ name }, i) => ({ [name]: values[i].value }));
console.log(result);

Answer 2

You could do this

const obj1 = [{name:'A'}, {name:'B'}, {name:'C'}];
const obj2 = [{value:1}, {value:2}, {value:3}];
const merged = Array.from({length:Math.min(obj1.length, obj2.length)}, (_,i) => {
 return { [obj1[i].name]: obj2[i].value };
});
console.log(merged);
