2.5 - Function Parameters & Return

Review

• Code is run line-by-line in a code file

• We can "chunk" code into "mini-programs" called functions

• We can "call" or run our custom functions as often as we want

• JavaScript has lots of built-in functions.

  • Some take parameters:  Math.min(10, 4, 29, 13, 1, 99, 2)

  • Some take no parameters:  Math.random()

  • Some give back (return) a value:  Math.random()  or  prompt("Pick a number from 1 to 10")

  • Some do not return anything:  console.log("Game Over")
