Welcome to the exciting world of desktop application development! If you're a web developer, you've already got a massive head start. Electron is a framework that empowers you to build cross-platform desktop applications using familiar web technologies: HTML, CSS, and JavaScript.
Think of Electron as a bridge. It takes your web development skills and lets you deploy them as native applications that can run on Windows, macOS, and Linux. This means you can leverage your existing knowledge and codebase to create powerful desktop experiences without needing to learn entirely new programming languages or paradigms for each operating system.
At its core, Electron combines two powerful open-source projects:

Chromium is the open-source browser project that powers Google Chrome. Electron uses Chromium to provide the rendering engine for your application's user interface. This means your HTML, CSS, and JavaScript are rendered just like they would be in a modern web browser, giving you access to a rich and familiar UI environment.
Node.js is a JavaScript runtime that allows you to execute JavaScript code outside of a web browser. Electron uses Node.js to provide access to the operating system's native functionalities. This includes things like file system access, interacting with the operating system's menus and notifications, and much more, opening up a world of possibilities beyond what's typically available in a browser.
This powerful combination allows Electron applications to have both a rich, interactive user interface (thanks to Chromium) and the ability to interact deeply with the underlying operating system (thanks to Node.js). This duality is what makes Electron so versatile for building desktop applications.
In essence, Electron lets you create desktop applications by packaging a web application with a runtime that can execute it. You write your application's UI using standard web technologies, and Electron handles the rest – providing the necessary environment to run it as a standalone desktop application.
