Create an array based on two objects

Question

I have two objects, that contains same number of properties:

object1: {
    prop1: 'data12',
    prop2: 'data13',
    prop3: 'data58',
    prop4: 'xyz',
    // more props here... 
  }

object2: {
    prop1: 123,
    prop2: '[email protected]',
    prop3: 'text',
    prop4: 'bla',
    // more props here... 
  }

I want to build an array {name: '', value: ''} based on this objects:

[
  { data12: 123 },
  { data13: '[email protected]' },
  { data58: text },
  { xyz: 'bla' },
]

How can you do that? The number of properties could be different.

Is the properties appear in both object?

Just using Object.keys() can do it

let object1 = {
    prop1: 'data12',
    prop2: 'data13',
    prop3: 'data58',
    prop4: 'xyz',
  }

let object2 = {
    prop1: '123',
    prop2: '[email protected]',
    prop3: 'text',
    prop4: 'bla',
  }
  
let result =[]
let obj = {}
Object.keys(object1).forEach(k =>{
  obj[object1[k]] = object2[k]
})
result.push(obj)

// combined with reduce can also do it
/*
let obj =Object.keys(object1).reduce((a,c) => {
  a[object1[c]] = object2[c]
  return a
},{})
*/ 

result.push(obj)


console.log(result)

what would be the best way to validate if the pops on obj1 and obj2 mismatch?
