Modifying the value of an object key with Javascript

The information I am working with is structured as follows:

obj = {
    pref: {
      language: 'English',
    }
};

My goal is to update the language field to 'Spanish'.

Answer №1

To set the language preference to 'Spanish' for the object, you have the options of either using obj.pref.language = 'Spanish' or

obj['pref']['language'] = 'Spanish'
.

Answer №2

To change the value of a key in an object, use dot notation

let myObject = {
  name: {
    first: 'John',
    last: 'Doe',
  }
};

myObject.name.first = 'Jane';

console.log(myObject)
