Thanks - but that's intended. Read the next explanation block - it's
contrasting expressions to declarations.

The above code gets transformed before execution starts.
I personally feel this explanation is confusing since var bar = function() {}; doesn't.

If it is intended to compare between two block, having two styles in the same block (function test(data) {) is confusing.

It does actually - var bar gets hoisted so bar is initialised to undefined throughout its scope. The declaration gets hoisted and initialised as a function.

Thanks for your reply!
