This methodology ought to be invoked on the record, specifying the type T as String within the filterIsInstance() function. Remember than in Kotlin, a map created with mapOf is immutable (read-only ), so that you can’t change its components after creation, if you strive do it, you’re going to get a compilation error should you try it. That’s why if we want to modify a map, we want to create an mutable map using mutableMapOf. By using these features, you’ll have the ability to easily create and initialize maps in Kotlin in accordance with your particular needs. The mapOf() function permits you to create an immutable map, guaranteeing that its content material can’t be altered once initialized.
