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
