prompter: is javascript back end or front end language?

assistant: JavaScript can be used for both front-end and back-end development. On the front-end, it is commonly used to add interactivity to web pages, such as form validation, animations, and dynamic content. On the back-end, it is often used with Node.js to create server-side applications, APIs, and to interact with databases. So, whether JavaScript is considered a front-end or back-end language depends on the context in which it is being used.

prompter: What are the top APIs, libraries, or development kits?

assistant: There are many APIs, libraries, and development kits available to use with JavaScript. In no particular order, some of the top APIs, libraries and SDKs are as follows:

-OpenWeatherMap: Provides access to global weather data for current conditions and forecasts.
-Stripe: Used for processing online payments, including credit card transactions and subscriptions.
-Google Guava: A general-purpose library that contains functions that can be used to save time by simplifying tasks.
-Log4j2/SLF4j: Two logging library alternatives to the one included in the JavaScript Development Kit.
-React: A library that includes tools used for building user interfaces.
-Node: An open source server runtime environment.

These are just some of many examples of APIs, libraries and development kits that are used with JavaScript on both the front-end and back-end, though there are many more that each serve their own specific functions.

assistant: There are numerous APIs, libraries, and development kits available for JavaScript development, and the most popular ones vary depending on the specific use case. However, some commonly used libraries for front-end development include React, Vue.js, and Angular, while for back-end development, popular libraries include Express, Koa, and Hapi. For APIs, tools like GraphQL and RESTful APIs are widely used. As for development kits, popular ones include React Native for mobile app development, Electron for desktop app development, and Jest for testing.

assistant: Javascript is a front end language.

prompter: What are the most common applications of Javascript in software development?

assistant: The following are some of the most common applications of JavaScript in software development:

- Dynamic web pages: JavaScript is commonly used to make web pages dynamic by providing interactivity to websites, such as prompts, alerts, and animations. It is also used for data validation in contact and sign-up forms and supports external applications like Flash, PDFs, and widgets. JavaScript enables users to load content onto a website without reloading the entire page.
- Web apps: JavaScript is well-suited for building web apps because it interacts with web browsers directly. It uses APIs that provide additional functionality to achieve better performance. By only requesting the data that’s needed, applications can avoid parsing and storing unnecessary fields, which uses resources more efficiently.
- Mobile apps: JavaScript is used to develop cross-platform mobile apps for iOS, Android, Windows, and Blackberry. Some of the most widely-used JavaScript frameworks for mobile apps include jQuery Mobile, React Native, Apache Cordova, and Titanium.
- Games: JavaScript is increasingly being used to create games like Angry Birds, Polycraft, and Bejeweled. When used with HTML5, JavaScript can create powerful games that require nothing more than a keyboard to play. The Ease JS library provides developers with simple solutions for working with rich graphics that are useful for creating games, generative art, and other highly graphical experiences.
- Server-side software: JavaScript is used to write server-side software through Node.js open-source runtime environment. Developers can write, test, and debug code for fast and scalable network applications. JavaScript helps to generate content and manage HTTP requests.
- Non-web contexts: JavaScript frameworks have been designed to facilitate mobile app development across various platforms like IOS, Android, and Windows. React Native framework allows cross-platform mobile app building, where developers can use a universal front end for Android and IOS platforms.
- Presentations: JavaScript can be used with HTML5 to create slideshows and presentations. The Reveal JS and Bespoke JS frameworks enable developers to create presentations.

JavaScript is also widely used in various segments, including Google, YouTube, Facebook, Wikipedia, Yahoo, Amazon, eBay, Twitter, and LinkedIn. The global job market boasts around 13.8 million JavaScript Developers, and JavaScript proficiency is a must-have for professionals interested in web development.

assistant: JavaScript is often used in web applications and may sometimes be used to power backend services. JavaScript is frequently used to power SPAs (single-page application) which is when a single page is served from the server, and the page is continuously updated locally by JavaScript.
