Learning Julia

By: Anshul Joshi, Rahul Lakhanpal

Overview of this book

Julia is a highly appropriate language for scientific computing, but it comes with all the required capabilities of a general-purpose language. It allows us to achieve C/Fortran-like performance while maintaining the concise syntax of a scripting language such as Python. It is perfect for building high-performance and concurrent applications. From the basics of its syntax to learning built-in object types, this book covers it all. This book shows you how to write effective functions, reduce code redundancies, and improve code reuse. It will be helpful for new programmers who are starting out with Julia to explore its wide and ever-growing package ecosystem and also for experienced developers/statisticians/data scientists who want to add Julia to their skill-set. The book presents the fundamentals of programming in Julia and in-depth informative examples, using a step-by-step approach. You will be taken through concepts and examples such as doing simple mathematical operations, creating loops, metaprogramming, functions, collections, multiple dispatch, and so on. By the end of the book, you will be able to apply your skills in Julia to create and explore applications of any domain.

Introduction to REST


REST is the underlying architecture that powers the most modern web application running on the internet. It offers a simpler form of architecture as compared to the traditional SOAP and WSDL-based ones.

Representational State Transfer (REST) is a simple way of sending and receiving data between the client and server, which is majorly done using HTTP and the data is transported or exchanged using a JSON format for the most part. It's a truly lightweight alternative to the Simple Object Access Protocol (SOAP)-based web applications.

REST uses HTTP methods such as GET, POST, PUT, and DELETE, for updating resources on the server. It provides the simplicity of a uniform interface as well as the scalability to support a large number of components.

The following are some architectural constraints that define a RESTful system as per Wikipedia. If a state is found violating any of these constraints, then the whole system may not be termed as RESTful:

  • Client-server architecture: The...
