I'm new to objects & methods and I'm creating a new key-value pair starting with an '_' (underscore) to see that it shouldn't be changed.
I just realized that I don't need to use the '_' when I create a getter method.
Why is that?
I am just learning about JavaScript and objects to be precise.
const team = {
_players: [{
firstName: 'Josh',
lastName: 'Huan',
age: 27
},
{
firstName: 'Greg',
lastName: 'Peterz',
age: 33
}
],
get players() {
return this._players;
}
};
I thought that I just use the '_players' as the reference to the getter method, like 'get _players()...' but instead I don't need to use underscore.
Thank you guys in advance!
I don't need to use the '_' when I create a getter method.
You don't "need" an underscore for anything. As you noted, the underscore marks properties which shouldn't be touched from outside, but that's just a convention. It's still a normal property name like any other.
What you need for your getter to work is just two different property names - one for the getter property and one for the data property that actually stores the value. You can use any two arbitrary property names for this.
