--description--

The character class \d is a shorthand for [0-9]. Replace this character class with the shorthand inside your first constraint tuple.

--hints--

You should turn the [0-9] class into \d.

js
({ test: () => assert.match(code, /constraints\s*=\s*\[\s*\(\s*nums\s*,\s*r("|')\\d\1\s*\)\s*,\s*\(\s*lowercase\s*,\s*r("|')\[a-z\]\2\s*\)\s*,\s*\(\s*uppercase\s*,\s*r("|')\[A-Z\]\3\s*\)\s*,\s*\(\s*special_chars\s*,\s*r("|')\4\s*\)\s*,?\s*\]/) })
