Contract

  1. escapeHtml escapes ampersand, double quote, single quote, less-than, and greater-than characters
  2. escapeHtml leaves strings without special HTML characters unchanged
  3. escapeHtml correctly handles strings containing only special characters or repeated characters
  4. escapeHtml converts non-string primitives and objects to strings before escaping
  5. escapeHtml handles empty strings returning an empty string
