## Scheme 6: Lambda video

Series: Feel the cool, Basics, Closures, Recursion, Quotation, Lambda, Macros.

Continuing the series on Scheme, this video explains the lambda function, which allows you to define anonymous functions. It goes on to bend your mind with 2 examples of the enormous power of functions and closures in Scheme.

## Scheme 5: Quotation video

Series: Feel the cool, Basics, Closures, Recursion, Quotation, Lambda, Macros.

Continuing the series on Scheme, this video explains on of the most powerful and unfamiliar features of Scheme: quotation. Quoting allows us to talk about and manipulate code in code, as easily as we deal with strings or numbers.

## Scheme 4: Recursion – how to write functions in Scheme video

Series: Feel the cool, Basics, Closures, Recursion, Quotation, Lambda, Macros.

Continuing the series on Scheme, this video describes the way you write code in Scheme: recursion. Recursive functions can be pretty efficient in Scheme, if you structure them right, and the video covers the concept of a tail call, which is the most important way of doing this.

## Scheme 3: Closures video

Series: Feel the cool, Basics, Closures, Recursion, Quotation, Lambda, Macros.

Continuing the series on Scheme, this video describes an important feature of functions in Scheme: closures. Closures allow functions to carry their “environment” around with them, and even change it later. This allows all kinds of exciting things, including implementing something similar to classes in other languages.
