If

If is one of the very basic concepts in programming. For example:

• If today is workday, go to work, else go to sleep.
• If the temperature is greater than 30, turn on the AC.

and so on

Add Node

Right-Click anywhere on canvas, select Flow Control/If

Connect Node

Based on Condition, the flow of our program will go either True or False, we can add separate nodes for each branch:

Try

Click the checkbox next to Condition and see the result

Dynamic Condition

Sometimes we need to use the result of other nodes to determine the branch, for example:

Try

Change the values in Equal node and see the result

Nested If

In some cases, we need to use If inside another If to achieve the following logic: if ..., else if ..., else ..., we can do this by using nested if, for example:

TIP

There is no constraints for the depth of nested If, however a good practice is to keep the depth of nested If as small as possible
