When using Express, it is possible to define endpoints with different paths:
app.get('/:foo*', function(req, res) { ... });
app.get('/:foo(.*)', function(req, res) { ... });
Although these two paths may appear similar, what sets them apart?

* represents zero or more occurrences of the preceding tokens
If we have the string /:foo/apple/banana/:foo/:1234
/:foo* matches: /:foo/apple/banana/:foo/:1234
^^^^^ ^^^^^
A capturing group like (.*) will match all characters that occur 0 or more times before it. This wildcard can match any characters until the end of the string
For example, if we have the string /hello/world/:foo/bar?id=123
/:foo(.*) matches /hello/world/:foo/bar?id=123
^^^^^^^^^^^^^^^^
