with ElectronJS developers can use the same codebase to create applications for Windows, Mac and Linux. this eliminates the need to write separate code for different platforms and making development faster and more efficient.

One of the main benefits of ElectronJS is that it allows developers to leverage their existing web development skills to create desktop applications. Developers can use popular web frameworks such as React, Angular or Vue.js to build user interface and Node.js to handle the backend logic.

This code creates  file input element and button. when the button is clicked, uploadFile function is called, which gets the first file from the input element, and logs the file’s name to the console.

you can then use fs module in Electron to read the file and perform any other operations you need.
