Coding conventions provide guidelines for programming style, practices, and naming to make code more consistent, easier to understand, and maintainable. They set standards for indentation, brace style, naming conventions, and other aspects so that collaborators can work together effectively and consistently. While different styles can work, it is important for a team to agree on and stick to shared conventions.

1. Why
Coding Conventions ?

2. –Wikipedia
“a set of guidelines for a specific programming
language that recommend programming style,
practices and methods for each aspect of a
piece program”

3. in most cases,
we’ll write
in a style that we want
$userName $username $user_name

5. consistent

6. easier to understand

7. maintainable code

8. –Paul M. Jones
“coding style not because one is better than
another, but because we need a standard by
which to collaborate”

9. indentation
tabs vs spaces

10. or…hit TAB and let the IDE do the conversion
for the appropriate number of space

11. brace style
Allman vs 1TBS

13. Android Code Style
Guidelines

14. in the end
it doesn't matter which
coding styles we pick.

15. what does matter is
everyone sticks with those
conventions and uses them
consistently.
