What is JavaScript? What can I build with it?

JavaScript is a programming language used to create interactive effects within web browsers. With JavaScript, you can create features like popup boxes, animations, interactive menus, form validations, and more. It allows you to make websites more dynamic and engaging for users. In The Complete JavaScript Course 2024, you’ll learn JavaScript from the basics all the way through advanced topics to become an expert JavaScript developer.

What can I build with JavaScript?

JavaScript powers the interactivity and dynamic behavior on most modern websites. With JavaScript, you can build things like web forms with validation, slideshows, toggled menus, interactive charts/graphics, single page web apps, browser games, web animations, and more. Advanced JavaScript frameworks even allow full featured web applications to be built.

Is JavaScript the same as Java?

No, Java and JavaScript are two completely different programming languages used for different purposes. JavaScript, which is covered in The Complete JavaScript Course 2024, is a lightweight scripting language run in web browsers used to create interactivity on web pages while Java is a robust and statically typed language run on servers and devices used to develop various applications. They have similar syntax but otherwise differ greatly.

What are the main advantages of JavaScript over other programming languages?

JavaScript is a very versatile, flexible, and lightweight language. Some of its key advantages are that it enables interactive web pages, runs on both the client and server side, has a simple syntax, integrates well with HTML and CSS, has a massive ecosystem of libraries and frameworks, allows cross-platform development, and it results powerful for advanced developers. The Complete JavaScript Course 2024 also focuses in making the language easy and enjoyable for beginners!

How does JavaScript enable dynamic web pages?

As Jonas Schmedtmann explains, JavaScript allows web pages to respond to user interaction and update content dynamically without needing to reload the entire page. Things like animating elements, validating forms, creating interactive widgets, updating content sections, and more are enabled by JavaScript running in the browser and manipulating the DOM in real-time. This allows much faster, smoother experiences.

What is asynchronous programming in JavaScript and why is it important?

Asynchronous JavaScript uses concepts like callbacks, promises, and async/await to handle long-running tasks without blocking execution. This allows non-blocking requests to servers and other I/O operations. It’s crucial for performance by preventing the UI thread from being blocked. Asynchronous JS has revolutionized network programming and given rise to interactive single-page apps.

How has the evolution of JavaScript engines improved performance?

Performance has dramatically improved thanks to JavaScript engines like Google’s V8 introducing just-in-time compilation, abstract syntax trees, inline caching, and other optimizations. Modern engines can directly compile JS to machine code at runtime, rather than interpreting line-by-line, allowing today’s JavaScript to rival native application development.

What are some key differences between client-side and server-side JavaScript?

Client-side JS runs in the browser to create interactive web pages, while server-side JS like Node.js runs on the backend to build fast network applications. Client-side has access to the DOM, while server-side focuses on databases and files. They also have different libraries and methods, but share much of the same core language familiarity.

How has JavaScript enabled more complex web applications?

As you will learn through The Complete JavaScript Course 2024, JavaScript allows web apps to have stateful interactivity without page reloads by manipulating DOM nodes directly. It enables real-time communication via WebSockets. JS also provides access to various device APIs for experiences impossible in static HTML, like graphics/audio processing, geolocation, camera/mic access, WebVR, WebGL, and WebAssembly. The rise of powerful JS frameworks now allows web apps rivaling native desktop apps.

Why has JavaScript recently gained traction also as a server-side language?

JavaScript is already ubiquitous browser-side, so being able to share code and paradigms server-side makes full stack development more efficient. Node.js enables scalable, event-driven server apps thanks to Chrome’s V8 engine also running server-side code. NPM offers the world’s largest software registry to reuse JavaScript modules. As microservices and serverless architectures emerge, JavaScript provides a productive language for both client-facing and backend applications.

How can JavaScript enable more secure applications?

JavaScript and Node enable various authentication mechanisms like OAuth and OpenID to securely identify users across websites. JWTs allow securely transmitting user details in tokens. Libraries like helmet and csurf provide protection against common attacks like cross site scripting and forgery. Following best practices like parameterization of queries and input validation also mitigate vulnerabilities. Strict Content Security Policies may be enacted.

What are some ways JavaScript powers artificial intelligence applications?

JavaScript machine learning libraries like TensorFlow.js and Brain.js allow training ML models and using them client-side in web apps for tasks like computer vision and natural language processing. Server-side libraries like Node-RED enable wiring together AI services, APIs, and real-time data feeds. JavaScript’s ubiquity, flexibility across devices/operating systems, and specialized math/matrix APIs have enabled it to become a capable language for powering AI apps.

How might JavaScript be used in Internet of Things devices?

Lightweight JS runtimes like Node Micro and JerryScript allow it to run on resource-constrained IoT hardware unable to support larger environments. JavaScript Object Notation (JSON) works well serializing sensor data to the cloud. JS enables prototyping and quick iteration on interface design through web tools. Full stack JS simplifies development by enabling reuse of skills and code between embedded and cloud/interface parts of a system. Library support for various communication protocols aids integration.
