In 2006, Google introduced a game-changing engine called V8 ⚙️, written in C++. This engine was designed to be an optimising compiler and interpreter for JavaScript. It was hidden within the Chromium browser and led to the development of Node and Dino 🦖, which allowed developers to harness the full potential of JavaScript. The V8 engine was instru...
JavaScript code is passed through the engine and converted into an abstract syntax tree. This abstract syntax tree can be executed through the Ignition interpreter or the top of an optimising compiler. The Ignition interpreter converts the code line by line into byte-code, while the top of an optimising compiler converts the entire code into an opt...
Today, there are many popular JavaScript engines available, each with its own strengths and weaknesses. Some of the most popular engines include SMP8, which is known for its fast startup times and low memory usage on Apple devices. Another newer runtime called Deno is written in the physics programming language, making it not only a runtime but als...
