Simply put, data iteration is to assign a number of numbers, one after the other, to the same variable, and once for each assignment, run the contents of do once.
for each item i in list Iterate over the contents of an array onto the variable i and run the contents of do once per iteration.
count with i from a to b by c Increased from a to b , the number of each increment is c , and the result of each increase is iterated to the variable i, and once per iteration, the content of do is run once.
break out of loop You can choose to jump out of the entire loop, or jump out of this loop, and execute when you execute the block.
Add an iterative block to the program, set the iteration parameters, and the do program that runs after each iteration. Example: Iterate the brightness of the RGB bar from 0 to 100.
