Loops in Coding
⭐ MasteredA loop repeats instructions many times so you don't have to write them again. 'Repeat 10 times: jump' is a loop.
Loops save coders from writing the same lines over and over.
All about Loops in Coding
A loop repeats a set of instructions many times, so you do not have to write the same code over and over. For example, repeat 10 times: jump would make a character jump ten times. Loops make programs shorter and more efficient.
There are different kinds of loops. Some repeat a set number of times, while others repeat until a condition changes. Programmers must be careful to design loops that eventually stop, or the program may run forever.
