JavaScript The Solution

Question about loops

Hi guys.

Just finished the practice loops workshop after giving JavaScript a break for a while.

What are the different use cases for while, doWhile and for loops if I can essentially do the same thing with each, as shown in the above mentioned workshop?

Thanks in advance Happy coding

Each type of loop is best suited to certain situations:

  • for β€” when you need to create and maintain a counter or index
  • while β€” when a non-counter condition will control the iterations
  • do...while β€” when the code must be performed before the condition is tested
