Why does the WHATWG URL API include the '#' character in the hash property, and how does this affect URL parsing?
AThe hash property includes '#' only if the URL uses HTTPS.
BThe hash property excludes '#' to simplify string operations on fragments.
CThe hash property is always empty because fragments are ignored in URL parsing.
DThe hash property includes '#' to clearly separate fragment; it must be handled when manipulating URLs.
Step-by-Step Solution
Solution:

  1. Step 1: Understand hash property format

    The WHATWG URL API includes the '#' character in the hash property to mark the start of the fragment.

  2. Step 2: Impact on URL handling

    This means when manipulating or comparing fragments, the '#' must be considered or removed explicitly.

  3. Final Answer:

    The hash property includes '#' to clearly separate fragment; it must be handled when manipulating URLs. -> Option D

  4. Quick Check:

    Hash includes '#' for clarity in URL fragments [OK]
Quick Trick: Hash includes '#' symbol; remove if needed for fragment only [OK]
Common Mistakes:
  • Assuming hash excludes '#' character
  • Ignoring fragment parts in URL parsing
  • Thinking hash depends on protocol
