Notes from Coding Standard review 6/16/21

Categories of standards:

• Stylistic
• Related to performance

Philosophy of coding guidelines (Kelly)

1. Readability <-- lowers conceptual load, especially moving between projects/languages
2. Uniformity / predictability <-- " "
3. Pit of success <-- "If you always do it this way, you'll avoid a lot of issues"

• "Why", not just "what" (Kevin)

How opinionated do we get?

• AVOID vs. DO NOT (Mark)
• "We are not going to take a stance on this ___"
  • We don't need to take an opinion on this
  • When do we need to be firm on something that's stylistic vs. not

CONSIDER: use when there's an exception
DO: when there's not an exception
