JavaScript is a scripting or programming language that allows you to implement complex features on web pages. Every time a web page does more than just sit there and display static information for you to look at—displaying timely content updates, interactive maps, animated 2D/3D graphics, scrolling video jukeboxes, etc.—you can bet that JavaScript is probably involved. It is the third layer of the layer cake of standard web technologies, two of which (HTML and CSS) we have covered in much more detail in other parts of the Learning Area.

AngularJS is a JavaScript open source front-end framework that is mainly used to develop single-page web applications (SPAs). It is a continuously growing and expanding framework that provides better ways for developing web applications. It changes the static HTML to dynamic HTML. It is an open-source project that can be freely used and changed by anyone. It extends HTML attributes with directives, and data is bound with HTML.

React is a JavaScript library used to build user interfaces. It is developed by Facebook. It simplifies creating dynamic and interactive web apps with the help of component-based architecture, reusability, and efficient rendering with the JSX and virtualDOM.

React JS is used to create single-page applications (SPAs). It is known for its component-based architecture, which allows you to create reusable UI components, making complex web applications easier to manage and maintain.

jQuery is a small, light-, and fast JavaScript library. It is cross-platform and supports different types of browsers. It is also referred to as ?write less, do more. because it takes a lot of common tasks that require many lines of JavaScript code to accomplish and binds them into methods that can be called with a single line of code whenever needed. It is also very useful to simplify a lot of the complicated things in JavaScript, like AJAX calls and DOM manipulation.

SASS, an acronym for Syntactically Awesome Stylesheets, emerges as a robust CSS preprocessor that enhances the capabilities of traditional CSS. It introduces features such as variables, nesting, mixins, inheritance, and more, enabling developers to craft CSS in a more concise and modular manner. SASS files employ the.scss extension and are compiled into standard CSS files that browsers can interpret.

PHP is a server-side scripting language created primarily for web development but is also used as a general-purpose programming language. Unlike client-side languages like JavaScript, which are executed on the user’s browser, PHP scripts run on the server. The results are then sent to the client’s web browser as plain HTML.

C++ is the most used and most popular programming language developed by Bjarne Stroustrup. C++ is a high-level and object-oriented programming language. This language allows developers to write clean and efficient code for large applications and software development, game development, and operating system programming. It is an expansion of the C programming language to include object-oriented programming (OOPs) and is used to develop programs for computers. This C++ Tutorial will cover all the basic to advanced topics of C++, like C++ basics, C++ functions, C++ classes, OOPs and STL concepts.

Java is an object-oriented, class-based programming language. The language is designed to have as few dependencies and implementations as possible. The intention of using this language is to give relief to the developers from writing codes for every platform. The term WORA, write once and run everywhere, is often associated with this language. It means whenever we compile a Java code, we get the byte code (.class file), and that can be executed (without compiling it again) on different platforms provided they support Java. In the year 1995, Java was developed.

Python is an interpreted, object-oriented, high-level programming language with dynamic semantics. Its high-level built-in data structures, combined with dynamic typing and dynamic binding, make it very attractive for Rapid Application Development, as well as for use as a scripting or glue language to connect existing components together. Python’s simple, easy-to-learn syntax emphasizes readability and therefore reduces the cost of program maintenance. Python supports modules and packages, which encourages program modularity and code reuse. The Python interpreter and the extensive standard library are available in source or binary form without charge for all major platforms and can be freely distributed.

Node.js is an open-source and cross-platform runtime environment for executing JavaScript code outside of a browser. You need to remember that NodeJS is not a framework and it’s not a programming language. Most of the people are confused and understand it’s a framework or a programming language. We often use Node.js for building back-end services like APIs like web apps or mobile apps. It’s used in production by large companies such as Paypal, Uber, Netflix, Walmart, and so on.

 A database refers to an organized collection of data stored electronically on a device. This allows us to access, manage and search more relevant information. Before the development of database systems, flat file systems were widely used to store data. The relational database approach is popular compared to the flat file model because it eliminates redundant data. For example, suppose we have employee and contact information stored in the same file. In such a case, multiple business contacts will show up in multiple queues

MongoDB stands proud as a leading NoSQL database, offering an open-source, document-orientated method that diverges from traditional relational databases. Unlike SQL databases, MongoDB stores statistics in BSON format, akin to JSON, making an allowance for greater flexibility in record storage and retrieval. In this article, We will get in-depth expertise about MongoDB.

SQL, short for Structured Query Language, often pronounced “sequel”, is the backbone of modern data management. It is a standard programming language used to communicate with relational database management systems (RDBMS). 

SQL empowers users to store, retrieve, manipulate, and analyze data in a structured and efficient manner. This guide explores SQL in depth, exploring its basics as well as advanced techniques, benefits, challenges, and how Atlassian supports the SQL experience.
