Javascript change the value of a key

Question

I have some data that looks like this:

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

I want to change the value of language to 'Spanish'

`obj.pref.language = ???` What exactly is the issue? Basic syntax? — Shilly, Feb 26 '19 at 15:07

You can simply use obj.pref.language = 'Spanish' or obj['pref']['language'] = 'Spanish'.

Use dot notation to access the key and change the value

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

obj.pref.language = 'Spanish';

console.log(obj)
