2/2 This is one of the reasons I like languages like F#, Scala and Rust. They default to immutable values but they give the developer the means to make things mutable if it's justified.

Another thing that language designers should be very aware of: defaults are extremely important! Most developers will never bother to use anything other than a default even if another choice would better suit the use case.

I mean how many people use an unsigned integer as an index in a looping construct? Yet consider how many times you've needed a negative index into, well, any data structure? But because signed integer is the default that's what usually ends up getting used!

I am going to be reading "How To Design Programs" and I thought others might like to read and discuss it so I set up a book club via Fable. https://fable.co/club/dettechwatch-book-club-with-onorio-catenacci-178852936285

Feel free to forward the invite.

The book is free and available online here: https://htdp.org/2024-11-6/Book/index.html

Please let others know about this! The more folks reading and discussing the book the more we can all learn!
