Using JavaScript, a common way to style elements is by adding and removing class values. Traditionally, this way involved parsing an element's className property, separating all of the elements into an array, making your class value changes, and serializing the array back into a string. This is the approach web developers and popular JS libraries have been using for centuries, but this approach isn't particularly fun. If you aren't careful, it is also easy to make mistakes.
