The obvious answer to that is "because you are familiar and comfortable with JS and don't want to (or ATM don't have time to) learn the ins-and-outs of another language and its ecosystem."

That seems to be one of the main drivers behind Electron's popularity, others being easier cross-platform support (or at least the perception of that) and the vote of confidence in its stability from the likes of MS using it in their products (primarily VSCode in MS's case).

What would be your alternate suggestion, and why? (genuine question rather than a rhetorical dig: I plan to tinker with Electron for a couple of projects soon so if there is something better (or simply that is a suitable alternative to consider) out there I'm not aware of, I'd like to be made aware)
