In general, code is something that stands for something else.

In computers, code is a series of instructions that tell a computer what to do.

What is coding?

  • coding (aka programming or software development) is a human activity
  • it's called code because what we write is not what the computer reads
  • to a computer, it's all ones and zeros; to us, it's words (and numerals and punctuation)

What is coding NOT?

  • coding is not mathematical
    • some logic
    • mostly just counting
  • coding is not solitary
    • most coding happens in a team
    • pair programming is awesome
  • coding is not about finding the right answer
    • there's always more than one way to do it
    • every solution has tradeoffs
    • there is always a better way, and never a perfect way
    • "The only perfect program is an empty file." - Alex
