Immutability: The listOf() function creates an immutable list, which means that the contents of the list cannot be modified once it has been created.

Here are some advantages and disadvantages of using the listOf() function in Kotlin:

Var number:float = 5.45 // Gives error as by default decimals are interpretted as double.

Var number = 5.45 // Interpreted as Double We can explictly do this by giving the type name Var text = 'hello' // Here Kotlin finds out text is of String type. Var for variable, which is mutable and can be re-assigned. Supports functional programming ( eg:Lambda functions) REPL : Similar to Swift REPL, Kotlin also have an REPL where in which we can try out expressions. Interoperable : Interoperable with Java and Android libs (In Kotlin, the type system distinguishes between references that can hold null and those that cannot.) Type interpretation is also present for some types. Safe: Exceptions are caught at compile time. (Type of a variable is known at compile time.) Kotlin is a statically typed programming language from JetBrains. Now Kotlin is officially announced for Android, I thought of getting started and below is my learnings, as an iOS developer, I am writing a comparison also whereever required.
