Understanding JavaScript Classes
Javascript Classes
JavaScript classes were introduced with ES6, offering a more convenient way to create and work with objects and prototypes. They provide a cleaner syntax for creating object-oriented code in JavaScript, allowing developers to define blueprints for objects along with properties and methods within a class. Classes can also inherit from other classes using the `extends` keyword, enabling the creation of class hierarchies and facilitating code reuse. Overall, JavaScript classes simplify the process of working with objects and prototypes in JavaScript, making the code more organized and easier to maintain.

1 - JavaScript Classes are a way to define a blueprint for creating objects. They provide a means for creating objects with properties and methods.
2) Classes in JavaScript are syntactical sugar over the existing prototype based inheritance. They offer a more familiar and cleaner syntax for creating objects and implementing inheritance.
3) The `class` keyword is used to define a class in JavaScript. Inside a class, you can define properties and methods that will be available to objects created from that class.
4) Classes can have constructors that are invoked when an object is created. This is where you can initialize the object's properties.
5) You can also define methods within a class to perform actions on objects created from that class.
6) Classes can have inheritance, where one class can inherit properties and methods from another class. This helps in reusability of code.
7) The `extends` keyword is used to create a class that inherits from another class in JavaScript.
8) JavaScript also supports the concept of static methods and properties within classes that belong to the class itself rather than individual instances.
9) Classes can be used to create multiple instances of objects that share the same structure and behavior, making them a powerful tool for organizing and managing code.
10) Understanding JavaScript Classes is essential for anyone looking to build modern web applications using the latest ECMAScript standards. Our training program covers in depth concepts and hands on exercises to help students master JavaScript Classes effectively.
