Answer 1

You can use reduce() and forEach() methods.

var data = [{name:'abcd', data:[1,2,3,4,5,6]},{name:'cdef', data:[7,8,9,10,11,12]}]
var result = data.reduce(function(r, {name, data}) {
 data.forEach((e, i) => {
 if(!r[i]) r[i] = {[name]: e};
 else r[i][name] = e;
 })
 return r;
}, [])
console.log(result)
