what is difference between val and var kotlin
// Kotlin difference between val and var
// val stands for read-only variable, and cannot be changed. (immutable variable)
fun main() {
val number = 1
number = 2 // Not possible.
}
// var stands for variable, and can be changed. (mutable variable)
fun main() {
var number = 1
number = number + 9
println(number) // this would return 10, because number got changed
}kotlin variable
val name = ”Marcin” // Can't be changed
var age = 5 // Can be changed
age++kotlin var val
