The IF component allows to conditionally execute other components based on a condition.
The component accepts a boolean expression as input and if the expression is true, it will execute the components that are between the IF and the ENDIF components.
number == 1
timestamp > new Date().getTime() * 1000
device_name == "John's iPhone"
