Kotlin infers the type of variable from the value assigned to it. In the following example, intVariable is assigned a type of Int:

    //Type Inference
    var intVariable = 10

Since Kotlin is type-safe, the following snippet will result in a compilation error if uncommented:

    //intVariable = "String" 
    //If uncommented -> Type mismatch: 
    //inferred type is String but Int was expected
