Regarding Route path

JavaScript
#1

Tell us what’s happening:

I have passed this test, but was wondering if the mark

:
inside "/:word is a must?
Why don’t we just use “/word”?
I tried both url path and it all show me the same result, so what’s the difference?

app.get("/:word/echo", (req, res) => {
  const { word } = req.params;
  res.json({
    echo: word
  });
});

I you’ll use word the path will match exactly /word/echo, but if you use :word then the path will match anything like /whateveryoulike/echo and whateveryoulike will be accessible as a variable inside the route handler.
