Variable can be declared as a val instead of var SC-R1061
Anti-pattern
Major
Scala allows you to declare variables using both var and val keywords. While var allows you to modify or re-assign values later on, val is strictly a constant, meaning you cannot change the value that was initially assigned. It is always recommended that you use val if you don't intend to modify or re-assign a variable.
Bad Practice
// `pi` is not re-assigned anywhere and can be declared as
// a `val` instead.
var pi = 3.14
Recommended
val pi = 3.14
