JavaScript Free Course for Beginners 2023 | JavaScript Tutorial | Code with Scaler

This is the second video of the JavaScript Tutorial for Beginners(2023) series by Code with Scaler. In this video, we have explained how Node.js handles tasks Asynchronously by using callbacks and concepts like, “event-loop”, “non-blocking”, “callback”, “asynchronous”, “single-threaded” and “concurrency”. We have also discussed how the call stacks the callback Queue and most importantly how the Event Loop work. An event loop is something that pulls stuff out of the queue and places it onto the function execution stack whenever the function stack becomes empty. A callback is a function passed as an argument to another function, this technique allows a function to call another function. A callback function can run after another function has finished. JavaScript is a single-threaded synchronous programming language and functions running in parallel with other functions are called asynchronous. This JavaScript tutorial for Beginners is the complete course that will be required to get started with JavaScript. We will be covering all the other topics also in upcoming videos in detail and with pdf notes and real-life examples.💡 Do Subscribe🧡so you don't miss the other essential videos, these can surely be gamechanger for your career and placement interviews!
