➡ HEX Formatting

[izzycodes02]

Check if the text that the user inputs is an actual HEX code by testing if it's in the HEX code formatting.

Solution

• Use hexCodeFormat = /^#?([a-fA-F0-9]{3}|[a-fA-F0-9]{6})$/; as the variable to test the input text against
• Use .test() to test the input text
• If the input text is not in that format, show an error message of "Incorrect HEX code!"
• The new if-statement show occurs after the '#' is at the front of the input text

Bonus ✨

• Check if the input text is a valid HEX code, not just formatted in a way
• Try var colorValue = parseInt(hexCode.slice(1), 16); and if (isNaN(colorValue) || colorValue < 0 || colorValue > 16777215){}
