How to compare an object with an array and return a value

Question

Say I have an object structured like this:

const carObj = {"1234":"Corvette","4321":"Subaru","8891":"Volvo"};

And I have an array that represents the key (or ID):

const myArray = [1234, 4321, 8891, 1234, 4321]

I want a loop, function, or something that will go through the object of arrays and return the value for the corresponding key. I am using vue.js and attempting to do this in a computed method. Any help would be much appreciated.

Expected output:

Corvette
Subaru
Volvo
Corvette
Subaru

Answer 1

Just map the numbers array the returns new one based on the keys of the object:

 const result = myArray.map(item=>carObj[item])

computed property:

computed:{
   result(){
        return this.myArray.map(item=>this.carObj[item])
      }

}

Answer 2

 const carObj = {"1234":"Corvette","4321":"Subaru","8891":"Volvo"}; const myArray = [1234, 4321, 8891, 1234, 4321]; myArray.forEach((item) => { console.log(carObj[item]); });
