What is the difference between boolean value true() and true.

As you have said, the main difference is the type, true being a Boolean and true() being a function (that returns a boolean).

I suspect that true() and false() exist to give the developer the option to use booleans in places where functions are expected, but this is speculation.

That is the only difference that I am aware of. One is a Boolean, the other a function. I am curious if anyone else has anything to say.

I also don't know of any differences. They should be able to be used in place of each other and the system still work as you intended it.

I have always wondered this as well, other than the obvious answer that one is a function. Maybe something like if you wanted to use the function version as an input for a looping function? Though, I can't really think of any case where that might be necessary.

I thinks true() is function where as true is literal value . apart from that I done see there is any difference as we can use true and true() interchangeably

I'm going to guess that there is no logical difference. The Appian documentation states: "true() returns true" and "Returns the Boolean value true."

docs.appian.com/.../fnc_logical_true.html

They work the same, but you should pick one and use it consistently to improve the readability of your code.

Hi Shubham Aware

true is a literal value of type boolean whereas true() is a function which returns it's output as true (literal) of type boolean.

It's similar as null and null() function

 

Please follow this link to have more understanding about literals

I think basic difference is Time and Space complexity
both are different types and used accordingly,

consider a scenario- create an array of {true,true,.......true} of length 50
common approach is repeat(true,50) which takes 5 to 10 Ms to execute the code but use less memory resource.

instead if you use apply(fn!true,enumerate(50)) it takes <1 Ms to execute
so this improves the performance, but use more memory resource because we are calling 3 functions

but apply function need function as 1st parameter but not the value.
so both true() and true looks same but used according to requirements.
