In Chapter 6, I learned how to create a group that contains the characteristics of this element. And learning to use the describe function in this group, and then finally define this describe, can make the code more convenient. Through Chapter 7, I learned about array, which is also to build a group, which can have many elements. If you want to know how many elements can be used, I also learned how to add and delete elements in a group, and how to list all elements in a group. In Chapter 8, I learned about how to change the case of elements, and I practiced how to use code to count elements. And through the overall practice, I have further mastered the for cycle.
