learn clojure

Both Java locks and CAS have an astonishing overhead (locks call local systems to block threads and cause high overhead ). The actor message queue has its own serious problems (using actor will greatly increase programming complexity ). Therefore, distributed development compromises the optimal solution based on business characteristics. In the case of concurrent writing with fewer reads and more: Clojure STM,Use multi-Version Control to change t

Explore how these next-generation JVM languages handle operator overloading Good ideas in programming languages can be extended and expanded into other languages, just like wine. Therefore, it is not surprising that the Java next-generation languages-groovy, Scala and clojure-have many common features. In this and next installment of the Java Next generation article, I'll explore the consistency of the feature list in each language syntax. I start wi

Defined"Functional Programming" is a programming paradigm (programming paradigm), that is, how to write a program's methodology. The main idea is to write the operation process as much as possible into a series of nested function calls.For example,

(Defprotocol X (cat [this other])Define a protocol, which is similar to the objective-C protocol. Different from Java interfaces. User => X {: On-interface user. x,: on user. x,: Sigs {: CAT {: Doc nil,: arglists ([this other]),: Name cat }},: var

(FN...) can be used to create anonymous functions, such: User => (FN [x] (+ 2 X) # Accept a parameter X and add 2. The above call defines a function using FN, but it is not executed. If you want to execute it immediately, you can add brackets
