You can defeat inlining by using closures:

    function thunk(x){ return function() { x() } }
    const thunkFoo = thunk(foo)
    const thunkBar = thunk(bar)

    for(var i = 0; i < 10000; i++) {
      thunkFoo()
      thunkBar()
    }

This is why the "Maybe you don't need Rust to speed up your JS" author was creating functions dynamically using `new Function()`.

Maybe you cal get away with

    function call(x){ x() }
    for(var i = 0; i < 10000; i++) {
      call(foo)
      call(bar)
    }

I didn't test the latter though, whereas the former is empirically slower if you call more than one thunk in your benckmark loop (a single thunk will have the call inlined).
