6,665 PointsWhy are we using strings?
Why are we using string in this? There are no strings printed to the page and .. well.. I just don't understand why in the world we're using strings?! Like this for example: 'rgb(' + red + ',' + green + ',' + blue + ')'
Can someone explain this..?

'rgb(' + red + ',' + green + ',' + blue + ')' would be to style a specific element. He's using rgb to define the style, and then concatenating this String with the values he's getting from the red, green and blue variables.

6,665 PointsWhere is this string being used?

6,665 Points"will be"? Cause it's not there now and I get the ten circles with different colors so what does it do?
John Lack-Wilson
8,181 PointsI may be wrong in my assumption here, but it seems like you are thinking that you should see the text displayed on the page somewhere? The text will be inserted into the code of the HTML document. The different colours you are seeing are related to the String that is being passed from JavaScript to HTML.

6,665 PointsI thought strings were used to write stuff... I don't really understand the concept of strings then I suppose.
John Lack-Wilson
8,181 PointsYou're partly correct. In this video a String is being used to write the code for the HTML document, in particular it's being used to style the colours of the circles by adding rgb(...).
