JavaScript Getters

JavaScript getters are special methods in objects that allow property-like access to computed values, defined using the `get` keyword. They enable encapsulation by letting developers control how a property is retrieved, often used for validation, lazy evaluation, or derived data. Getters are part of the ECMAScript 5 standard and are widely supported in modern JavaScript environments.

Also known as: JS getters, getter methods, property getters, accessor methods, get functions

Why learn JavaScript Getters?

Developers should learn and use getters when they need to abstract complex logic behind simple property access, such as calculating derived values from other properties or enforcing read-only access to sensitive data. They are particularly useful in object-oriented programming for creating more intuitive APIs, like in classes where a `fullName` getter concatenates `firstName` and `lastName`, improving code maintainability and reducing boilerplate.
