functions
A function takes inputs, runs code and (optionally) returns an output.
TouchDevelop functions are similar to mathematical functions. Consider the function that computes the square of x: square(x) = x*x. In code, it would look like this:
export function square(x: number) : number {
let result: number
return x * x
return result
}
private function
An function can be marked as private in the properties. A private function is not visible outside a library (if the script is a library)
documentation
The comment(s) at the beginning of a function used to provide a description of its purpose. This text will show in the help area when the function is called from the code editor. This is particularly useful for libraries.
