Something like

    if ('Bun' in globalThis) ...
    if ('Deno' in globalThis) ...
    if ('window' in globalThis) ...

could be used to determine the runtime.

That certainly works for Bun and Deno, not sure about what is effective in Node, though.

Checking for process.versions.{node,bun} works, not sure if Deno has an equivalent.
