Scala functional Programming Design principle first lesson programming paradigm (programming Paradigms)

I've been using Scala for a year or two, and the language seems to have a magical power that people don't want to let go of when they use it. Scala has had a very profound impact on my entire program life, and I learned about functional programming, so I know that there is an elegant, efficient, powerful language in the world.Scala is very popular abroad, but som

The inverse attack of Scala and Clojure functional programming language

the course, and 10,000 of them have passed the course certification, as evidenced by the popularity of the program. The functional gene of Scala,clojure, a part of the object-oriented lineage, is more pure, and it comes from a pedigree of Lisp. Paul Graham, who has praise the productivity of Lisp in the hacker and painter, has no doubt about his status. The author Michael Bevilacqua-linn uses these two JVM languages to explain the functional

A function can be used as a standard object: it can be treated as an input parameter or a result value of another function. Functions that accept a function as an input parameter or return another function as a result are called higher order functions (high order function). The use of anonymous functions (anonymou

Geotrellis using (vi) Scala concurrent (parallel) programming

This article is mainly about Scala concurrent (parallel) programming, then why the topic is called Geotrellis use (vi), mainly because this series explains how to use Geotrellis, the specific previous several blog has been introduced. I think the basis of doing any one thing is very important, like the college entrance examination or a variety of examinations, teachers will emphasize the basis, which is ver

How Scala programming is selected

(Bus). Only through horizontal expansion (scale out), that is, distribution expansion by increasing the computer server and then using the distributed computing technology to divide the computational task into discrete servers for processing; This is the core of big data technology.Predictably, we will face the future: distributed data, high concurrency processing, parallel computing, NoSQL and very large interactive complex network platform programming

Scala Programming (i)

About ScalaScala is a "stretched language", which can be changed and grown with the needs of the user. Scala can be used in a wide range of programming tasks, as small as scripts to build systems. Scala runs on the standard Java platform and can interact seamlessly with all Java libraries. It adds object-oriented and functional
