Nowadays, most programmers have much more experience in developing web applications than desktop applications. Even if we would like to add the ability to add the desktop application development into our toolset, it's too costly for us in terms of time and effort. We would have to invest in learning a new programming language to get it done, which is not a simple thing. Electron helps you in this situation by using your existing skill set. You don't have to learn anything other than web technologies such as HTML, CSS, and JavaScript.
