encodeURI — ampersand not encoded

📖 Usage Example
encodeURI('a=1&b=2')   // → 'a=1&b=2'
// & and = are valid URI characters

encodeURI() does not encode & or = because they are valid URI characters.

encodeURI Preserves &

encodeURI('a=1&b=2') does not encode & (it is a valid URI character).

Challenge: Verify & is preserved.

💡 Hints (1)
  • • encodeURI preserves characters that are valid in a full URI including & = and ?.
