In this chapter, we have covered expressions, including conditionals and enough loops to make anyone dizzy. One of the major points to remember about loops and conditionals is that they run on Boolean values or expressions that evaluate to Boolean values. Also, remember that any statement block you open with a curly bracket must be closed by a curly bracket as well. And lastly, remember when comparing strings, Flash will interpret a lowercase letter differently than the same letter in uppercase because Flash evaluates the ASCII code points of the character, not the character itself.
Continue to play with the structure and conditions of loops to really get a good feel for them and what can be accomplished using them.
