Code is not Math

Equality is Weird

  • = does not mean “equals” it means “set a value”
  • == means “equal”
  • === also means “equal”

Programmers start counting at 0

  • var potatoes = [0, 1, 2, 3, 4, 5]

Coordinates a Grid are Different

  • Y-Axis Up is Negative, Down is Positive
  • X-Axis Left is Negative, Right is Positive.

Variables work differently

  • x = x+1 is valid.
  • It means take value x, then SET x to what it was plus 1.
