Question

I have this form of data coming from an API and I want it to convert into different structure in JavaScript .

For clarification . The 1 , 2 3,...etc are the coin id of each coin and the data coming in previous code is coming from 6 sources . hence its coming as object of objects and that too separately . Now I want it this way where for each coin all the data is segregated to one single object . Hope I am clear in terms of the problem . Any help would be highly appreciable.

Try this one , const newArr = arr.reduce((acc, c) => { const keys = Object.keys(c); for (i of keys) acc.push(c[i]); return acc; }, []); — Mithat Ercan

Its not adding properties for the same coin from other objects together . Few changes is required in this code. BTW thanks for the help . — Vedant Singh

This should also work:

const res={};

console.log(res)

There are two nested loops:

the outer one over all ids
and the inner one over all properties of the objects found in the outer loop
