Array method on the string.
So are you saying that we can call array index on the string? When I checked in the console I did:
let color = #F1111; console.log(color);
And I got back 'F'. Which means we can use bracket notation to access particular character of the string, even though string is not an array. How crazy is that? It gets even better:
let color = '#F1111'; let colors = ['#F1111', '#F2222', '#F3333']; console.log(colors); F
Which means every simple, basic array is in fact two dimentional array (from the point of view of the each character, if I may think like that). Eureka!

Some string operations are similar to array operations, but they are not the same thing. Using a bracket on a string is essentially the same thing as using the "charAt" method (which is not an array method).
colors" could be re-written as "
colors.charAt(1)", since "
colors" is an array but "
colors" is a string.
But you're right that you can treat an array of strings as a two-dimensional array of characters, just bear in mind that unless all strings are the same size it is a "jagged" array.
Thank you for this clarification.
