Example
Functions are declared using the fun keyword, followed by a function name and any parameters. You can also specify the return type of a function, which defaults to Unit. The body of the function is enclosed in braces {}. If the return type is other than Unit, the body must issue a return statement for every terminating branch within the body.
fun sayMyName(name: String): String {
return "Your name is $name"
}
A shorthand version of the same:
fun sayMyName(name: String): String = "Your name is $name"
And the type can be omitted since it can be inferred:
fun sayMyName(name: String) = "Your name is $name"
