(error: reassignment to val)
If you’ve already had the same error message as me, there’s an error between the chair and the keyboard. And in ignorance of what is the difference between val and var.
The difference between val and var is that val makes a variable immutable and var makes a variable mutable. Because val fields can’t vary, some people refer to them as values rather than variables.
Immutable: In object-oriented and functional programming, an immutable object (unchangeable[1] object) is an object whose state cannot be modified after it is created
