Python Vs Nim: Functions
View function_example.nim
# args are immutable by default.
# Variables immutables by default (std lib).
# func ensures exampleFunction dont have Side Effects (is a Functional function).
func exampleFunction(arg: Natural): range[0..100] = # Static Types no type Bugs possible (wont compile otherwise). range[0..100] only allows integers from 0 to 100. Natural only allows integers not Negative (>=0).
# result variable is automatically created for you (you always need to return a result anyways)
preconditions arg > 0, arg < 101 # Preconditions (like a Unittest BEFORE a block of code, asserts on args and variables)
postconditions result > 0, result < 101 # Postconditions (like a Unittest AFTER a block of code, asserts on result)
result = arg + 1 # Mimic some logic here, it does not really matter for this example
# result is automatically returned, no need for "return result" (can still use return if wanted tho)
