I swear Electron is incredibly fast in every instance I've used it. Unless you're doing heavy computation with complex algorithms, it's really nice. I don't believe VS Code has to do any computationally expensive computations, and it enables many more people to work on a project (JavaScript being a truly universal language).
I'm currently working on a Mail application and my benchmark test case is an email account with 20,000 emails to be displayed. Noting we currently have no lazy loading and all these are loaded from an on-disk database and put inside their own Shadow DOM it truly did surprise me when it took just over 400ms for an entire page load on my development laptop (~3 years old with an i5, nothing special).
Even if you need to do complex algorithms, just write that particular part in C and use it in the rest of your JS code like normal.
