What is Node.js?

Node.js is a popular tool used by developers worldwide to run JavaScript outside of a web browser. It facilitates website development by offering numerous programming modules that greatly enhance project work. Node.js was built in C++ using Google's V8 engine and enables the compilation of JavaScript source code into machine language. Its impressive performance allows it to handle multiple requests simultaneously, making it more popular than even the widely-used Apache server.

Node.js overview

Node.js is a single-threaded application runtime environment that resolves scalability issues and provides non-blocking input/output support. It enables developers to use JavaScript for both frontend and backend development, capitalizing on its popularity and adherence to the ECMA Script standard. The platform's efficient library and dependency management through NPM (Node Package Manager) feature essential tools like Gulp, Express, Grunt, jQuery, and React. Written in C++, Node.js ensures high application reliability, performance, and speed.

Global adoption and accessibility

The accessibility of Node.js is enhanced by its relatively low entry threshold, as many developers are already proficient in JavaScript. Notably, global giants like Google, Microsoft, Netflix, LinkedIn, and PayPal utilize Node.js for its robust capabilities. Amazon's use of Node.js for serverless applications in cloud projects further underscores its suitability for modern, scalable web solutions.
