So, basically I have three questions regarding the codes.
1. How come there are three equal signs in first statement and how they work actually? Is this an assignation of value?
2. Where do I start to read the codes? From top to bottom and from left to right?
3. After text(), it can be seen that there are a few lines of codes wrapped in { }. What are the meaning of the codes?
I think that's all. Thanks for spending time to help me
