5 Most common SAIL functions that is useful for building an end-to-end application

Question

Hi Sail Wizards out there, 
 I am finding it increasingly vital to be able to use functions in Appian. Apart from things the if(), index(), cast() ect... 
 What are some of your favourite functions and why? Ones that are less well known would be great. 
 A list of 3-5 would be awesome. Happy to do the learning/reading up but I first need to know about the funxtions! 
 Many thanks, Eric

I don't believe in favorites. They're all beautiful and unique in their own ways. 
 
 I would recommend reviewing the documentation for each of them here . There aren't too many. Additionally, you can find helpful information in the function recipes , query recipes , and interface recipes documentation.

Hi erics171 It all depends upon the requirement, and based on requirements we need to use various functions. 
 
Hence it's very difficult to call few of them as useful / favorite. 
 
Instead i would recommend you to go through the Function & Interface recipes.
