It’s not much of a problem once you have code splitting. React supports code splitting, which lets you split large amounts JS into separate production JS files; load only what’s necessary at first, and load the rest as-needed: https://reactjs.org/docs/code-splitting.html https://reactjs.org/docs/code-splitting.html With a new programming language (like Zig), I would hope that they eventually try to have code splitting be automatic and transparent. For JS targets, you create multiple smaller final JS files instead of one giant JS file. For native targets, you could break out extra code into dynamically loaded .so or .dll files. The real challenge is making this whole process as painless and transparent as possible for the developer.
