Node.js transforms JavaScript from a browser-only language into a server-side runtime, enabling the development tools necessary for modern block development. Download and install it like any standard application from nodejs.org.
While PHP runs on web servers to generate HTML, and browser JavaScript adds interactivity to pages, Node.js uses Chrome’s V8 engine to run JavaScript on your computer directly.
Block development tools are written in JavaScript and run on your machine during development. Node.js enables these build tools, bundlers, and compilers that transform your modern JavaScript code into browser-compatible output.
