You're comparing apples to oranges. Lua is a language runtime. Electron is a full browser and a language runtime. If you want to compare them then compare node.js or JavaScriptCore to lua. Or compare Electron with a lua runtime that has a webkit/chromium engine integration. I don't especially like Electron, and sometimes like writing lua, but the two are not solving the same problem or competing in the same space.
