push key and values pair in object using loop in Javascipt

Hi I'm a beginner in javascript and trying to create a function that gets two objects as an argument, and in function, I want to create a new object which has keys of second object and value from the first object and if there's an extra key comes then will print same as it is in my created object

Output should be { Actor: "Programmer", firstName: "Bobo", shoeSize: 100 }

const obj = { 
  name: 'Bobo', 
  job: 'Programmer', 
  shoeSize: 100 
};

const obj2 = { 
  name: 'firstName', 
  job: 'Actor' 
}

function joinArray(data, data2){
  var a={};

  for(var key in data){
    if(key in data2){
      a{data2.key} = data{key}
    } else {
      a{data2.key} = data{key}
    }
  }

  return a
}

console.log(joinArray(obj, obj2))

You can also do that

const  obj = { name: 'Bobo', job: 'Programmer', shoeSize: 100 } 
const obj2 = { name: 'firstName', job: 'Actor' } 

function joinArray( data, keyNames)
  {
  let rep = {}
  for (let k in data)
    rep[((keyNames[k]) ? keyNames[k] : k)] = data[k]
  return rep  
  }

console.log( joinArray(obj,obj2) )
.as-console-wrapper {max-height: 100%!important;top:0;}

OR:

const  obj = { name: 'Bobo', job: 'Programmer', shoeSize: 100 } 
const obj2 = { name: 'firstName', job: 'Actor' } 

const joinArray = (data, keyNames) => 
  Object.keys(data ).reduce((rep,k) =>
  {
  rep[((keyNames[k]) ? keyNames[k] : k)] = data[k]
  return rep  
  },{}) 
 
console.log( joinArray(obj,obj2) )
.as-console-wrapper {max-height: 100%!important;top:0;}

const obj = { 
  name: 'Bobo', 
  job: 'Programmer', 
  shoeSize: 100 
};

const obj2 = { 
  name: 'firstName', 
  job: 'Actor' 
}

function joinArray(data, data2) {
  var a={};

  for(var key in data) {
    if(key in data2) {
      a[data2[key]] = data[key]
    } else {
      a[key] = data[key]
    }
  }

  return a
}

console.log(joinArray(obj, obj2))
