Purpose

Most programming languages provide for, while, recursion loop statements. Which one is best?

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
