Local variable inference

Local variable inference simplifies our code. Type inference makes our code strictly typed. We don’t need to use types everywhere in the program. It is not necessary to use type for a local variable. It will infer the type at the time it is first accessed in the program.
var num;
type(num); // print Unknown<0>
num = 100;
type(num); // print Int
Here initially num has not been typed. So, it is showing type of Unknown. Then we assign a value of 100 and it then treats the variable as num.
