Clojure Programming

In the course Clojure Programming from SpiralTrain participants learn to program in the dynamic and functional programming language Clojure.

Clojure Intro

The course starts with an overview of the features of functional programming and how these are supported by Clojure. Attention is paid to expression evaluation, immutability and concurrency support. It also demonstrated how the REPL loop in Clojure can be used to run code.

Clojure Syntax

Subsequently the variables and data types of the Clojure language and the control flow constructions in Clojure are discussed. Exception handling is also treated.

Functions

Functions are of course a central element in a functional language like Clojure and it is discussed how functions work in Clojure. In addition to standard functions, anonymous functions, variadic functions and higher order functions such as map and reduce are also on the course program. The passing of functions as parameters and returning functions as return value is also treated.

Data Structures

Data Structures in Clojure are covered as well including sequences, lists, sets, vectors, maps and hash maps. And also attention is paid to the operations on data structures such as unions and intersections of sets and the sorting of maps.

Advanced Types

Also advanced types such as predicates, atoms, agents and watchers are discussed.

Multiple Threads

Finally it's time for multiple threads and concurrency in Clojure. In this respect object locking, transactions, agents and asynchronous calls are treated.

Audience Course Clojure Programming

The course Clojure Programming is intended for anyone who wants to learn programming in the functional programming language Clojure.

Prerequisites Course Clojure Programming

In order to participate in this course basic knowledge of programming in another programming language is beneficial to the understanding but is not required.

Realization Training Clojure Programming

The theory is discussed on the basis of presentation slides. The theory is explained further through demos. After discussing a module there is the possibility to practice. Course times are from 9.30 to 16.30.

Certification Clojure Programming

After successful completion of the course the participants receive an official certificate Clojure Programming.
