When describing problems using ‘each’ or ‘every’, the chances are high that loops can help. Testing each position for screw placement. Finding every viable design.
Repeat the same part of your workflow a number of times specified by a certain number or a certain condition being met. ‘Loop’ means a workflow, the end of which is connected to the beginning.
Define the part of the DNA to be iterated and the starting values
Define how many times the workflow is repeated
Define the control structure such as a break statement for the termination of the loop
Loops help you to avoid building the same workflow multiple times.
