@ -5,11 +5,7 @@ Generates a random hexadecimal color code.
Use `Math.random` to generate a random number and limit that number to fall in between 0 and 16 using `Math.floor`. Use the generated random number as index to access a character from 0 to F. Append it to `color` till the length is not `7`. Use `Math.random` to generate a random number and limit that number to fall in between 0 and 16 using `Math.floor`.
