0x00 Lesson
You’ve made it to the end of the fourth part of this series, so let’s summarize:
- Loops let us repeat code until a condition is false.
- The most common loop is
for, which assigns each item inside the loop to a temporary constant. - If you don’t need the temporary constant that
for loops give you, use an underscore instead so Swift can skip that work. - There are
while loops, which you provide with an explicit condition to check. - Although they are similar to
while loops, repeat loops always run the body of their loop at least once. - You can exit a single loop using
break, but if you have nested loops you need to use break followed by whatever label you placed before your outer loop. - You can skip items in a loop using
continue. - Infinite loops don’t end until you ask them to, and are made using
while true. Make sure you have a condition somewhere to end your infinite loops!
