JavaScript is a lightweight, cross-platform, interpreted scripting programming language that is primarily used for client-side scripting. It’s built into both Java and HTML. On the other hand, Node. js is a server-side scripting language based on the Google Chrome V8 engine.
Read moreWhat is Node JS simple explanation?
Node. js is a JavaScript runtime environment that achieves low latency and high throughput by taking a “non-blocking” approach to serving requests . In other words, Node. js wastes no time or resources on waiting for I/O requests to return.6 Nis 2020
Read moreDo we need to compile Nodejs?
No need to install node and npm to deploy the compiled application. No need to download hundreds of files via npm install to deploy your application. Deploy it as a single independent file. Put your assets inside the executable to make it even more portable.
Read moreWhy node JS is single threaded and fast?
It’s partly due to the fact a multi-threaded program can run on multiple cores but the main reason, by far, is that when a thread is waiting for some IO operation (which is very often, especially in a server), the other threads can still progress .
Read moreHow does NodeJS event loop work?
The Event Loop takes the timer with the shortest wait time and compares it with the Event Loop’s current time . If the wait time has elapsed, then the timer’s callback is queued to be called once the call stack is empty. Node. js has different types of timers: setTimeout() and setInterval() .
Read moreHow does JavaScript event loop work?
The Event Loop has one simple job — to monitor the Call Stack and the Callback Queue . If the Call Stack is empty, the Event Loop will take the first event from the queue and will push it to the Call Stack, which effectively runs it. Such an iteration is called a tick in the Event Loop.
Read moreHow does the node js server work?
Node is completely event-driven. Basically the server consists of one thread processing one event after another . A new request coming in is one kind of event. The server starts processing it and when there is a blocking IO operation, it does not wait until it completes and instead registers a callback function.24 Ara 2015
