JavaScript is internally compiled by V8 with just-in-time (JIT) compilation to speed up the execution. This has been happening since 2009, when the SpiderMonkey JavaScript compiler was added to Firefox 3.5, and everyone followed this idea. JavaScript is generally considered an interpreted language, but modern JavaScript engines no longer just interpret JavaScript, they compile it. On the web, there is a race for performance that's been going on for years, and we (as users and developers) benefit a lot from this competition because we get faster and more optimized machines year after year. V8 is always evolving, just like the other JavaScript engines around, to speed up the Web and the Node.js ecosystem. the V8 official site), and they change over time, often radically. In this V8 introduction, we will ignore the implementation details of V8: they can be found on more authoritative sites (e.g.

It is portable and runs on Mac, Windows, Linux and several other systems. V8 is written in C++, and it's continuously improved.

V8 was chosen to be the engine that powered Node.js back in 2009, and as the popularity of Node.js exploded, V8 became the engine that now powers an incredible amount of server-side code written in JavaScript. This key feature enabled the rise of Node.js. The cool thing is that the JavaScript engine is independent of the browser in which it's hosted. The DOM, and the other Web Platform APIs (they all makeup runtime environment) are provided by the browser. It's the thing that takes our JavaScript and executes it while browsing with Chrome. Once you are done, you will feel confident in your JavaScript skills and be ready to move into libraries like React or Vue, or continue down your JavaScript journey.V8 is the name of the JavaScript engine that powers Google Chrome. This way, you can be sure that the concepts really stick with you. This is exciting, as you will deploy this extension to your Chrome browser, so that you get to experience it out in the wild.īetween each of the project sections, I will stress-test your skills with practice sections. Who knows, perhaps this little app marks the start of your career as a game developer?įinally, you will build your very own Chrome Extension. Moving on, you will build your very first game, namely Blackjack, the iconic Casino game.
This will teach you the very basics of JavaScript and the DOM. You will start out simple with a Passenger Counter app.
Instead of long and boring theoretical lessons, you will dive head-first into building products and solving challenges. So say goodbye to "tutorial hell" and get ready to start feeling your JavaScript superpowers grow exponentially.Īnother unique thing with this course is that you will build projects from the very start. It contains 140+ coding challenges, meaning that you will finally build that ever-so-important JavaScript muscle memory. This is perhaps the most interactive JavaScript course ever recorded. If you answer YES to any of the above questions, then this is the course for you. Do you think JavaScript is difficult to learn?ĭo you struggle to transition from watching JS tutorials to building JS projects?ĭoes regular coding courses sometimes bore you to death?
