56. Working With Classes - The Complete JavaScript Course 2024: From Zero to Expert!

The Complete JavaScript Course 2024: From Zero to Expert!

Discover how to work with classes in JavaScript, a fundamental aspect of object-oriented programming (OOP) that allows developers to create reusable and modular code. Classes provide a blueprint for creating objects with shared properties and behaviors, enabling developers to model real-world entities and interactions in their applications. In JavaScript, classes were introduced in ECMAScript 2015 (ES6) as syntactic sugar over the existing prototype-based inheritance model. Classes simplify the process of defining object prototypes and constructor functions, making it easier to create and manage object instances. To define a class in JavaScript, developers use the class keyword followed by the class name and a code block containing class members, such as properties and methods. Class properties represent the state of an object, while methods define its behavior and functionality. When working with classes, developers can use constructor methods to initialize object properties and set initial values. They can also define getter and setter methods to access and manipulate object properties, encapsulating behavior within the class and promoting data integrity. In addition to instance methods, classes support static methods, which are associated with the class itself rather than its instances. Static methods can be used for utility functions, factory methods, or other operations that don't require access to instance-specific data. Classes in JavaScript facilitate inheritance through the extends keyword, allowing developers to create subclass hierarchies and inherit properties and methods from parent classes. This enables code reuse and promotes modular design by allowing developers to extend and customize class functionality as needed. As you work with classes in JavaScript, consider best practices for class design, such as favoring composition over inheritance, keeping classes small and focused, and following naming conventions for clarity and consistency. These practices promote code readability, maintainability, and scalability in your projects. In summary, working with classes in JavaScript is a powerful way to create reusable and modular code, enabling developers to model complex systems and behaviors effectively. By mastering class-based programming techniques, developers can build more robust, maintainable, and scalable JavaScript applications. The modern JavaScript course for everyone!

About the course

The modern JavaScript course for everyone! Master JavaScript with projects, challenges and theory. Many courses in one! Why is this the right JavaScript course for you? This is the most complete and in-depth JavaScript course on 360 (and maybe the entire internet!). It's an all-in-one package that will take you from the very fundamentals of JavaScript, all the way to building modern and complex applications. You will learn modern JavaScript from the very beginning, step-by-step. I will guide you through practical and fun code examples, important theory about how JavaScript works behind the scenes, and beautiful and complete projects. You will become ready to continue learning advanced front-end frameworks like React, Vue, Angular, or Svelte. You will also learn how to think like a developer, how to plan application features, how to architect your code, how to debug code, and a lot of other real-world skills that you will need in your developer job. And unlike other courses, this one actually contains beginner, intermediate, advanced, and even expert topics, so you don't have to buy any other course in order to master JavaScript from the ground up! But... You don't have to go into all these topics. This is a huge course, because, after all, it's "The Complete JavaScript Course". In fact, it's like many courses in one! But you can become an excellent developer by watching only parts of the course. That's why I built this course in a very modular way, and designed pathways that will take you through the course faster. By the end of the course, you will have the knowledge and confidence that you need in order to ace your job interviews and become a professional developer. I know how students learn JavaScript and what they need in order to master it. And with that knowledge, I designed the ideal course curriculum. It's a unique blend of real-world projects, deep explanations, theory lectures, and challenges, that will take you from zero to an expert and confident JavaScript developer in just a couple of weeks. So what exactly is covered in the course? Build 5 beautiful real-world projects for your portfolio! In these projects, you will learn how to plan and architect your applications using flowcharts and common JavaScript patterns Master the JavaScript fundamentals: variables, if/else, operators, boolean logic, functions, arrays, objects, loops, strings, and more Learn modern JavaScript (ES6+) from the beginning: arrow functions, destructuring, spread operator, default arguments, optional chaining, and more How JavaScript works behind the scenes: engines, the call stack, hoisting, scoping, the 'this' keyword, reference values, and more. Deep dive into functions: arrow functions, first-class and higher-order functions, bind, and closures. Deep dive into object-oriented programming: prototypal inheritance, constructor functions (ES5), classes (ES6), encapsulation, abstraction, inheritance, and polymorphism. [This is like a small standalone course] Deep dive into asynchronous JavaScript: the event loop, promises, async/await, and error handling. You will use these to access data from third-party APIs with AJAX calls. [This is like a small standalone course] Learn modern tools that are used by professional web developers: NPM, Parcel, Babel, and ES6 modules Take this course if you want to gain a true and deep understanding of JavaScript Take this course if you have been trying to learn JavaScript but: 1) still don't really understand JavaScript, or 2) still don't feel confident to code real apps Take this course if you're interested in using a library/framework like React, Angular, Vue or Node in the future Take this course if you already know JavaScript and are looking for an advanced course. This course includes expert topics! Take this course if you want to get started with programming: JavaScript is a great first language!
