Express.js is a minimal and flexible Node.js web application framework that provides a robust set of features for web and mobile applications. It is designed to be easy to use and extend, and it is used by a wide variety of developers, from beginners to experienced professionals. Some of the features of Express.js include: Routing: Express.js provides a powerful routing system that allows you to..

setTimeout, setImmediate, and process.nextTick are all functions that allow you to schedule a callback function to be executed after a delay. However, they work in different ways and have different performance implications. setTimeout(): setTimeout() schedules a callback function to be executed after a specified number of milliseconds. The callback function is placed on the event queue, and the ..

In Node.js, the event loop is a fundamental part of its architecture and is crucial for handling asynchronous operations efficiently. It allows Node.js to perform I/O operations and other tasks without blocking the execution of other code. Understanding the event loop is essential for writing scalable and performant Node.js applications. Here's an overview of how the event loop works in Node.js:..

"Single-threaded" and "multi-threaded" are terms used to describe how a program or a software application manages and executes multiple tasks or threads of execution. These concepts have significant implications for how programs handle concurrency, responsiveness, and performance. Let's explore the differences between single-threaded and multi-threaded environments: Single-Threaded: Definition: ..

In Node.js, blocking and non-blocking refer to how I/O (input/output) operations are handled by the runtime environment. Understanding the difference between these two approaches is crucial for building efficient and responsive applications, especially in scenarios with high concurrency, such as web servers. Let's explore both concepts: Blocking I/O (Synchronous): In a blocking or synchronous I/..

In the context of Node.js, "bindings" typically refer to native bindings or C/C++ addons. These are modules that allow you to integrate existing C or C++ code into your Node.js applications. This capability is essential when you need to interact with low-level system libraries, hardware, or existing C/C++ codebases from your Node.js application. Here's an overview of Node.js bindings: Native Add..
