Do getters and setters provide encapsulation?

Having getters and setters does not in itself break encapsulation. What does break encapsulation is having a getter and a setter for every data member (every field, in java lingo). That is one step away from making all data members public.

Should you use getters and setters in JavaScript?

Conclusion. You don’t necessarily have to use getters and setters when creating a JavaScript object, but they can be helpful in many cases. The most common use cases are (1) securing access to data properties and (2) adding extra logic to properties before getting or setting their values.

Should I use setters and getters?
