Programing Language Design. Loop and Iteration. (2025)

For Coders. on Programing Language Design. Loop and Iteration.

• It would be a good exercise, if you look into each of these functions, and try to implement it in python or your fav language.
• You'll learn a lot.
• (all these, can be done with loop or nested loop with states.)

• Wolfram: Iteration

you'll learn:

• The concept of these functions, and get a sense all possible things one might want to do with a list or array.

• The design of language for a given algorithm. E.g. To generated nested rectangular array, python has list comprehension. Wolfram lang is just a function Table.
• Can you specify, exactly, how they differ?
• Can you specify, what are the pros and cons of each design?
• Can you say, which is easier to implement?
• Can you say, which is easier to understand?
• Can you say, which is easier to use, or type?

• e.g. for recursion, Wolfram language has a Nest, that allow recursion of any function.
• this in my view, is much simpler, more powerful, than function def that call itself.

• If you try to implement them all, that makes a great exercise.
• Instead of code golf or leet code or advent of code or whatever current fashion.

• JS: Array.prototype
• Elisp: Sequence. Iteration Guide
