9,910 Pointsunderstanding getters and setters
maybe it's just because i didn't made enough practice with OOJS, but i think i don't understand what getters and setters are used for. I would like a practical explanation of why they are used in a real life situation please

229,732 PointsSome common benefits of using accessor methods (getters and setters):
- it gives simpler syntax
- it allows equal syntax for properties and methods
- it can secure better data quality
- it is useful for doing things behind-the-scenes
And a code example:
var person = {
firstName: "John",
lastName : "Doe",
get fullName() {
return `${this.firstName} ${this.lastName}`;
}
};
The object here stores only first and last names, but the getter provides access to the full name, with the same syntax as a property, and combining the other properties "behind-the-scenes".
