Question

  category : [\'a\',\'b\',\'c\'],
  title : [\'e\',\'f\',\'g\'],
         


        

Answer 1

You can use map() and forEach()

var obj = {
  category : ['a','b','c'],
  title : ['e','f','g'],
  code : ['z','x','v']
}

var result = Object.keys(obj).map(function(e, i) {
  var o = {}
  Object.keys(obj).forEach((a, j) => o[a] = obj[a][i])
  return o
})

console.log(result)
