My name is Dody Gunawinata and I primarily develop using C#. #Different ways to write function literals In its simplest form, it looks as follows:Ībove is a type for a function that takes no parameter and returns a Unit (void in other language parlance)Ībove is a type for a function that takes no parameter and return a StringĪbove is a type for a function that takes a string and returns nothing.Ībove is a type for a function that takes two parameters (String and Float) and returns nothing.īecause a function type is just a type, it means that you can assign it to a variable, you can pass it as a function argument and you can return it from a function. Function Types and Function LiteralsĪ function type is a type consisted of a function signature and function return type that are separated by -> operator. Since vararg creates an array, you simply use the * operator to pass one vararg to another. '$firstName $lastName' for simple variable name or '$ ')

Kotlin has string templates, which is awesome.So there is no need to stuff your functions as static members of classes like what you do in C# or Java. Like JavaScript, you can create functions outside classes.Unlike Java, you do not need to match your file name to your class name.Comments are similar to Java or C#, /* This is comment */ for multi line comments and // for single line comment.Kotlin project website is at .Īll the codes here can be copied and run on Kotlin online editor.
