Complete the code below using the method that returns the position of the darkred string inside the colors array:

const colors = [ 'tomato', 'crimson', 'darkred', 'firebrick' ];

I'm super stuck and I couldn't tell you why. Thank you for reading and helping in advance! I have to fill in: colors. ('darkred'); // 2

Both of indexOf() and arr.includes() didn’t work for me.
