Clojure Training Course

Who should attend

Developers who are interested in learning the advantages that Functional Programming can bring. The course is especially suited to Java developers, because will discuss interoperation with Java code

Prerequisites

While knowledge of Functional Programming is not required, delegates should be experienced at programming in a high-level language such as Java, C# or C++.
