Before we dive into the best practices, let's define some terminology and find out what is a "Best Practice".  

Coding Style—A coding style is a set of guidelines that specify how your code should look. The guidelines are helpful to ensure your code is easy to read and maintain. Coding styles can include such things as indentation, using tabs vs spaces, line length, naming of variables, and more.  

Coding standard—A coding standard is a set of conventions regulating how your code should be written. These conventions usually include code style and formatting but can also further define how a variable should be treated and used.  

Best practice—A best practice is a method or technique for coding that has consistently shown results superior to those achieved with other means. Best practices can include a combination of styles and standards.
