Getters should be function but

In JavaScript, a getter is a method that gets the value of a specific property. It allows you to access the property as if it were a regular variable, but behind the scenes, a function is called to retrieve its value.

Here is an example of using a getter in JavaScript:


const person = {
  firstName: 'John',
  lastName: 'Doe',
  
  get fullName() {
    return this.firstName + ' ' + this.lastName;
  }
};

console.log(person.fullName); 
// Output: "John Doe"


In the above example, we have an object called "person" with two properties: "firstName" and "lastName". However, we also define a getter called "fullName" which concatenates the first and last name. 

To access the full name, we simply use person.fullName as if it were a regular variable. Behind the scenes, the getter method is called and returns the desired value.

Using a getter allows us to dynamically calculate or retrieve values each time they are accessed. It provides a cleaner and more intuitive syntax for accessing properties.

Getters are particularly useful when you want to perform some logic or computation before returning a value. They can be used to retrieve values from a private or internal state of an object, perform data validation, or compute derived properties.

Note that the "get" keyword is used to define a getter. It should be followed by the property name with the first letter capitalized (in camel case) and a pair of parentheses to indicate that it is a function.

Overall, getters are a powerful tool in JavaScript that enhances the flexibility and maintainability of your code.
