Definition: Accessor refers to a component that has an interface. An accessor is a method, property or variable which allows you to interact with the data stored in it. In other words, an accessor provides access to the data. Accessors are often used as part of UI components to provide access to the user's data by providing methods to manipulate it. An example of an accessor would be a property in an object that can be accessed like this: ```javascript let person = { name: "John Doe", age: 25, email: "johndoe@example.com" }; console.log(person.age); // Output will show "25" // Accessor is being used to access the user's data by using methods available on the object. ``` In the code above, `age` is an accessor because it has a getter method (`getAge()`), and an setter method (`setAge(25)`). The getter method provides the current age of the person (which can be accessed through `person.age`), while the setter method allows you to set the age.
