    Javascript Promises in depth with V8 engine internals

    JavaScript is often perceived as slow and not scalable due to its single-threaded nature. However, for I/O intensive tasks, JavaScript (particularly NodeJS) performs well by delegating I/O operations to the underlying OS threads and continuing with other tasks. The post explains the blocking and non-blocking nature of JavaScript, the role of C++ APIs, and how async programming works using callbacks, promises, and the event loop.

    Understanding Concurrency, Parallelism and JS

    Concurrency and parallelism are often confused, but they have distinct differences. Concurrency involves handling multiple tasks by interleaving, while parallelism means performing them simultaneously. Threads can run concurrently or in parallel, depending on the CPU's number of cores. Node.js, though single-threaded, uses Worker Threads to manage blocking tasks, simplifying concurrency for developers. Understanding how Node.js handles concurrency can help avoid issues like race conditions, making programming more efficient and less error-prone.

    How JavaScript is Executed

    JavaScript execution within web browsers involves JavaScript engines like V8 in Chrome and SpiderMonkey in Mozilla. The process includes parsing the code into tokens, compiling it via Just-in-Time compilation into machine code, and then execution with garbage collection handling unused variables. JavaScript operates in both development mode on a local server and in production mode on a remote server. Beyond browser environments, Node.js allows JavaScript to run outside of browsers, enabling server-side development, mobile apps, desktop applications, and more.
