Bun's bundler claimed the bottom place in my recent analysis of how JavaScript tools handle generating inline script tags[1], because despite making lofty promises about being able to bundle applications into standalone HTML files, it produced a baffling combination of spurious syntax errors and miscompilations when presented with tricky code.
I'm pretty sure the version I tested was the Zig one (have they made a stable release of the Rust rewrite yet?). So I can definitely see how Bun's move-fast-and-break-things philosophy would have been a poor fit for the Zig community, even prior to the Rust rewrite.
