Small overview about Clojure?

What is Clojure?

Clojure is a robust, practical, and fast programming language with a set of useful features that together form a simple, coherent, and powerful tool.

Clojure is a dynamic, general-purpose programming language, combining the approachability and interactive development of a scripting language with an efficient and robust infrastructure for multithreaded programming. Clojure is a compiled language, yet remains completely dynamic – every feature supported by Clojure is supported at runtime. Clojure provides easy access to the Java frameworks, with optional type hints and type inference, to ensure that calls to Java can avoid reflection.

Clojure is a dialect of Lisp, and shares with Lisp the code-as-data philosophy and a powerful macro system. Clojure is predominantly a functional programming language, and features a rich set of immutable, persistent data structures. When mutable state is needed, Clojure offers a software transactional memory system and reactive Agent system that ensure clean, correct, multithreaded designs.

Small Overview about Expo CLI?

What is Expo CLI?

Expo CLI is a command line interface for developing Expo apps. It also includes a web-based interface (Expo Dev Tools) for using some of the most often used features also from a quick to use graphical interface.

Expo apps are React Native apps which contain the Expo SDK. The SDK is a native-and-JS library which provides access to the device's system functionality (things like the camera, contacts, local storage, and other hardware). That means you don't need to use Xcode or Android Studio or write any native code, and it also makes your pure-JS project very portable because it can run in any native environment containing the Expo SDK.

Expo also provides UI components to handle a variety of use-cases that almost all apps will cover but are not baked into React Native core, e.g. icons, blur views, and more.

Finally, the Expo SDK provides access to services which typically are a pain to manage but are required by almost every app. Most popular among these: Expo can manage your Assets for you, it can take care of Push Notifications for you, and it can build native binaries which are ready to deploy to the app store.

Small Overview about JEST ?

What is Jest?

Jest is an open JavaScript testing library from Facebook. Its slogan is "Delightful JavaScript Testing". While Jest can be used to test any JavaScript library, it shines when it comes to React and React Native.

Main Benefits

1) Developer Ready

Complete and ready to set-up JavaScript testing solution. Works out of the box for any React project.

2) Instant Feedback

Fast interactive watch mode runs only test files related to changed files and is optimized to give signal quickly.

3) Snapshot Testing

Capture snapshots of React trees or other serializable values to simplify testing and to analyze how state changes over time.

Jest is used by Facebook to test all JavaScript code including React applications. One of Jest's philosophies is to provide an integrated "zero-configuration" experience.

NPM and Yarn Command for Installation.

npm install --save-dev jest

yarn add --dev jest
