Getting Javascript object property by name

Question

Imagine I have an object like:

var obj = {
  name: {
    value: 'Sergio'
  },
  lastName: {
    value: 'Tapia'
  }
}

I want to create a function that grabs the value of a given property.

Ideally:

console.log(getProperty(obj, 'name'));
=> 'Sergio'

console.log(getProperty(obj, 'lastName'));
=> 'Sergio'

Answer 1

You can use bracket notation to access the property on the object. Your function would be:

function getProperty(obj, property) {
  return obj[property].value;
}

I would probably name it getProperyValue instead.

Answer 2

function getProperty(obj,property){
  return obj[property].value;
}

Answer 3

This function should help you achieve what you need.

function getProperty(obj, key){
  return obj[key].value;  
}

I believe

console.log(getProperty(obj, 'lastName'));

should return 'Tapia' rather than 'Sergio'.
