In this exercise, we were asked to create an immutable list: https://www.codecademy.com/courses/learn-kotlin/lessons/kotlin-lists/exercises/creating-an-immutable-list

I tried typing the syntax without taking advantage of Kotlin’s type inference, but it wasn’t accepted:

var waterSports: List<String> = listOf("Wind Surfing", "Sailing", "Swimming", "Jet Skiing", "Water Skiing")

instead, they accepted this:

var waterSports = listOf("Wind Surfing", "Sailing", "Swimming", "Jet Skiing", "Water Skiing")

Just curious, what’s wrong with the first syntax? The exercise did not show how it should be written without type inference, so I just had to look it up from other resources, but wasn’t sure if I got it correctly.
