Exercise 2: Confirming the Array Capture — Possible Solution
====================================================================

app.get('/*splat', async (req, res) => {
  console.log(req.params.splat);
  res.send('check the console');
});

VISITING /programming/general-purpose-languages/java
------------------------------
The logged value is:

  ['programming', 'general-purpose-languages', 'java']

a real JavaScript array with three separate string elements - not a
single combined string like 'programming/general-purpose-languages/java'.

CONTRAST WITH RAILS' *path
------------------------------
Per the Rails rebuild's own Chapter 3, Rails' *path glob captures the
entire matched segment directly as one string -
params[:path] would equal
'programming/general-purpose-languages/java' already joined, with no
extra step needed. Express 5's own *splat instead requires an
explicit .join('/') call to produce the equivalent single string,
since it captures an array of the individual segments rather than a
pre-joined string.

WHY THIS WORKS AS AN ANSWER
------------------------------
It correctly demonstrates req.params.splat is a real array via a
direct console.log, and correctly contrasts that array-capture shape
against Rails' own single-string *path capture from an earlier
chapter in the series.
