6,260 PointsCan someone explain me this line of code?
$newColor.css("background-color", $("#newColor").css("background-color"))
I understand that we're changing the background color of the variable $newColor, but adding the value $("#newColor").css("background-color") throws me off.

What is happening here is explained better than me in the prior video: perform part 2. He explains that the css method takes two arguments, the "getter" and the "setter" so what it is saying is get the css style background and apply it to the the id newColor background-color. I hope this makes sense. I would suggest watching the prior video as he I think explains its best.

6,260 PointsThanks Jacob. I understand it now. I think what confused me was the variable name $newColor was pretty similar to the jquery object name. All clear. Thanks!

23,117 PointsI agree, the var name is a little confusing. I'm glad I could help.

23,117 Pointsthe variable name is the jquery object, its the id name that is the same. the id name is stated with a # sign, and its the same name as the variable jquery object

Jacob Mishkin
23,117 PointsJohn, that is correct. This is a perfect example of why its important to clearly and properly name your variables. As we can see naming your variable the same as the id name of the div might not be the best choice, for people who are beginning to learn jQuery. So outside of knowing the difference between $newColor and #newColor, Its more important to name variables that are clear, concise, and can be easily distinguished.
