understanding 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

Some 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".
