for

  • I know how many repeat needed
  • Cannot repeat with certain condition (need to use if and break)
  • Hard to use previous result to next repeated loop
  • Good usage example : print numbers in array.

while

  • I do not know how many repeat needed
  • repeat with certain condition
  • Hard to use previous result to next repeated loop
  • Good usage example : count how may words you typed

recursion

  • I know how many Stack Memory that will use
  • repeat with certain condition
  • Easy to use previous result to next repeated loop
  • Good usage example: find 88th’s Fibonacci number

additional considerable conditions

  • Does your programming language provide tail recursion
  • Program environment such as embedded, Android, or Web
