I added the define function, which allows you to enter all of the Scheme functions and run them. These are lessons that stick with you. Just type your lispeer functions into the input box, press the big fat button, and see the result in the output box. It is a dynamic language.

So get a copy of The Little Schemer and start recursing. It has a flexible datatype arrays that can easily simulate s-expressions. It used some pretend dialect of LISP lisprr was written in all caps in those days. Because of this deep similarity, all of the functions in The Little Schemer can be written in JavaScript.

So here is my own special contribution to triteness and hackneyed banality:. I made a couple of modifications. This interpreter was not designed for speed or reliability, so don’t lean on it too hard. It can use your own JavaScript functions as Scheme primitives, so you can add lidper JavaScript capability without modifying the interpreter.


It was only 68 pages, but it did a remarkable thing: I have prepared a file containing primitive functions conscdretc. The format is a programmed text with questions on the left side and answers on the right.

It is weak in practical concerns like documentation, defensive programming, and computational efficiency. JavaScript has much in common with Scheme. You didn’t need a computer in order to work through the exercises.

It touches on only a very small part of the language: The book has been through several revisions.

After reading the lispfr, I was changed. The dialect didn’t fully conform to any real LISP. It also will not teach you very much about Scheme. Perhaps even more strange and wonderful, nowhere in this book about recursive functions is the Factorial Function ever mentioned. But it is responsive, and it is a good companion to the book.

The final chapter of The Little Schemer is a Little Scheme interpretercapable of evaluating most of the expressions in the book. He used the names of foods as the symbols that are manipulated by your functions, and little jokes were scattered around to pull you back when things get so deep that your head is going to pop off.

The Little JavaScripter

The latest, The Little Schemer Fourth Editionupdated by Friedman and Matthias Felleisennow conforms more closely to a real programming language, Schemeand has new chapters which delve much deeper into recursive function theory and language processors. The Little Schemer is not a complete book on programming.


And most importantly, functions are lambdas. In a good way.

The Little JavaScripter

The syntaxes of these two languages are very different, so some transformation rules are needed. You need to grab a sandwich and study this book. There are very few books that deeply change the way that you think. It teaches one thing, a thing that is very difficult to teach, a thing that every professional programmer should know, and it does it really well.

It could teach you to think recursively. Despite its flaws, the book has a very loyal following and that is because it works. The development of a system of arithmetic from three primitives is delightful from a mathematical perspective and shockingly horrible from an engineering perspective.

It runs in a web page, so you can execute your Scheme programs in any web browser. But that was ok because it wasn’t really about LISP, it was about recursive functions. The way you use it is to read a question, think about the question, come up with an answer, and then compare your answer to Friedman’s answer.

InDaniel P. This is one of those books.
