It might be tempting to assume what many people have believed about Node.js, the most common definition of it being that it’s a runtime for the JavaScript language. Familiarity with Node.js semantics ( require, fs).While some of these claims are true, we will dig deeper into the Node.js runtime, understanding how it runs JavaScript, seeing whether it actually is single-threaded, and, finally, better understanding the interconnection between its core dependencies, V8 and libuv.
Companies such as Netflix, Uber, and LinkedIn give credibility to the claim that Node.js can withstand a high amount of traffic and concurrency.Īrmed with basic knowledge, beginner and intermediate developers of Node.js struggle with many things: “It’s just a runtime!” “It has event loops!” “Node.js is single-threaded like JavaScript!” Since the introduction of Node.js by Ryan Dahl at the European JSConf on 8 November 2009, it has seen wide usage across the tech industry. In this article, we will learn about what makes up Node.js, give it a meaningful definition, understand how the internals of Node.js interact with one another, and explore the project repository for Node.js on GitHub.
With its high level of concurrency, it has become a leading candidate for people choosing tools to use in web development. Node.js is an interesting tool for web developers.
