What is the difference between getters and setters in programming?

Getters and setters are methods used to access and modify the values of an object's properties. Getters retrieve the value, while setters update it.

Can you give me an example of how they are used in a class?

Sure! In a class, a getter method might look like this: getName() { return this.name; } and a setter like this: setName(newName) { this.name = newName; }.

Why should I use getters and setters instead of accessing properties directly?

Using getters and setters allows for better control over how properties are accessed and modified, enabling validation and encapsulation.

Are there any performance implications of using them?

Generally, the performance impact is minimal, but using them can add a slight overhead due to the method calls. However, the benefits often outweigh this.
