Lisp is a family of programming languages known for their:
* Symbolic nature: They manipulate symbols and data structures directly, making them great for artificial intelligence and symbolic computation.
* Homogeneity: Code and data are represented in the same way (often as lists), allowing for powerful metaprogramming techniques.
* Extensive use of parentheses: This syntax can be initially intimidating, but leads to a highly expressive and flexible language.
Common Lisp dialects include:
* Common Lisp: A standardized dialect with a large library of features.
* Scheme: A simpler dialect known for its elegance and functional programming features.
* Clojure: A modern dialect running on the Java Virtual Machine.
Here's a basic example of Lisp code (in Scheme):
```scheme
(define (square x)
(* x x))
(square 5) ; Returns 25
```
