Loops
Looping
Sometimes you need to execute logic several times. If that is needed you can create loops within NoCode-X. You can loop within NoCode-X in 2 different ways:
Loop functions
The safest way to execute loops of logic is by using functions.
Functions that can be used are:
- For each: Loops over a list of items & executes an action for each item.
- For: Executes an action x amounts of times defined by a start number, end number & increment amount
More information on these functions can be read in the Functions section.
Recursion
You can also create loops by using recursion. This is where you actually call the action that you are executing at the moment with different parameters. This can be constructed by using the "Execute action" function.
Endless loops
In some occurrences because of a programmers' error, programs can enter "Endless loops". If this happens this is always a bug in the application you are building & can have effects on the usage of the application.
However within NoCode-X you are protected in most cases for endless loops. Using the functions you are by default protected to never encounter endless loops, there is always a built in maximum amount of times we will execute an inner action.
Using recursion you are also protected by a built in maximum. However the maximum is much higher here as it is much harder to detect.
Beware: If you create a loop by using an data-format action trigger such as "Update data" and in the action you actually update the same data again, this can result in an endless loop you are not protected against.
