Are you new to JavaScript and want to learn how to use the Getter feature? This tutorial will help you understand what a Getter is, how it works, and how to use it in your code. We will also discuss the benefits of using Getters in your JavaScript code.
const user = {
firstName: 'John',
lastName: 'Doe',
get fullName(firstName, lastName) {
return `${firstName} ${lastName}`;
}
};
user.fullName('John', 'Doe') // returns 'John Doe'
Getters can also be used to create computed properties. For example, if we wanted to create a property that returns the user's initials, we could use a getter like this: const user = {
firstName: 'John',
lastName: 'Doe',
get initials(firstName, lastName) {
return `${firstName.charAt(0)} ${lastName.charAt(0)}`;
}
};
user.initials('John', 'Doe') // returns 'JD'
Getters can be very useful for retrieving complex data from an object, and for creating computed properties. They are also very easy to use, and can be used to make your code more readable and maintainable.
