JavaScriptHardstringsregexvalidation

Instructions

Create a function that determines whether a string is a valid hex code.

A hex code must begin with a pound key # and is exactly 6 characters in length. Each character must be a digit from 0-9 or an alphabetic character from A-F. All alphabetic characters may be uppercase or lowercase.

Examples

isValidHexCode("#CD5C5C") ➞ true

isValidHexCode("#EAECEE") ➞ true

isValidHexCode("#eaecee") ➞ true

isValidHexCode("#CD5C58C") ➞ false
// Length exceeds 6

isValidHexCode("#CD5C5Z") ➞ false
// Not all alphabetic characters in A-F

isValidHexCode("#CD5C&C") ➞ false
// Contains unacceptable character

isValidHexCode("CD5C5C") ➞ false
// Missing #
