Electron JS is an open-source framework that enables developers to build cross-platform desktop applications using web technologies like JavaScript, HTML, and CSS. By combining the Chromium rendering engine and Node.js runtime, Electron JS allows web-based apps to run as native desktop programs on Windows, macOS, and Linux. While it simplifies app development and deployment, Electron JS can also be exploited by cybercriminals to distribute malware disguised as legitimate desktop applications. Security best practices are essential when developing or using Electron JS apps to minimize vulnerabilities and prevent unauthorized code execution.
