# Tips
1.Important functions first
2.Follow user input
3.Hardcoded secrets and credentials
4.Use of dangerous functions and outdated dependencies
5.Developer comments, hidden debug functionalities, configuration files, and the .git directory
6.Hidden paths, deprecated endpoints, and endpoints in development
7.Weak cryptography or hashing algorithms
8.Missing security checks on user input and regex strength
9.Missing cookie flags
10.Unexpected behavior, conditionals, unnecessarily complex and verbose functions
