✳
A way to repeat instructions without writing them again and again.
Start with the idea
A loop repeats a block of code until a condition is met. It saves time and keeps programs short.
A for loop repeats a set number of times, while a while loop keeps going as long as a condition stays true.
Be careful of infinite loops, which never stop because their condition never becomes false.
