MongoDB is latest on our blog, It tops all big 4 It companies!


MongoDB provides high availability with replica sets. A replica set consists of two or more copies of the data. Each replica-set member may act in the role of primary or secondary replica at any time. All writes and reads are done on the primary replica by default. Secondary replicas maintain a copy of the data of the primary using built-in replication. When a primary replica fails, the replica set automatically conducts an election process to determine which secondary should become the primary. Secondaries can optionally serve read operations, but that data is only eventually consistent by default. If the replicated MongoDB deployment only has a single secondary member, a separate daemon called an arbiter must be added to the set. It has a single responsibility, which is to resolve the election of the new primary. As a consequence, an idealized distributed MongoDB deployment requires at least three separate servers, even in the case of just one primary and one secondary.

ReactJs is a very popular library for importing integrated ui components


React (also known as React.js or ReactJS) is a free and open-source front-end JavaScript library[3] for building user interfaces based on components. It is maintained by Meta (formerly Facebook) and a community of individual developers and companies.[4][5][6] React can be used to develop single-page, mobile, or server-rendered applications with frameworks like Next.js. Because React is only concerned with the user interface and rendering components to the DOM, React applications often rely on libraries for routing and other client-side functionality.[7][8]

How Node.js became a new rival for every backend language there?


This guide is for anybody looking to learn more about how Node.js works, its pros and cons and how it can help deliver tangible business results. We’ll begin by defining what Node.js is and give a brief history of its development, before listing some pros and cons, with examples to highlight them. There’ll also be some tips on how to host and maintain Node.js applications and how Node.js compares with other programming languages. It is used for server-side programming, and primarily deployed for non-blocking, event-driven servers, such as traditional web sites and back-end API services, but was originally designed with real-time, push-based architectures in mind. Every browser has its own version of a JS engine, and node.js is built on Google Chrome’s V8 JavaScript engine. Sounds a bit complicated, right?. In simple terms, what this means is that entire sites can be run using a unified ‘stack’, which makes development and maintenance quick and easy, allowing you to focus on meeting the business goals of the project. The fact that Node.js is open source means that it is free to use and constantly being tweaked and improved by a global community of developers. An important thing to understand about Node.js is that it is actually neither a framework or a library - as with traditional application software -, but a runtime environment.











Programming Language

How Javascript become the King of web development programming language?, Its been used from frontend part to backend


Libraries are collections of prewritten code that can be used to easily implement frequently used JavaScript tasks. Libraries lead to faster development because developers don’t need to write every line of code. Frameworks are collections of libraries. Think of libraries as tools. And frameworks as fully loaded toolboxes. Although a library can provide code for a specific function on your website, a framework can provide all the code you need to build the website. Common JavaScript libraries include jQuery and React. Common JavaScript frameworks include Vue.js, Node.js, and Angular. What Is JavaScript Used For?. JavaScript is most commonly used to create dynamic, interactive websites. Developers use JS to add animations, pop-up windows, search bars, buttons, audio and video, chat widgets, and other interactive elements to a webpage. You can also use JS to provide real-time updates to a page without reloading it. For example, websites with news tickers, stock or crypto prices, or real-time product availability information typically use JavaScript to add this functionality. The front end (user-facing side) of many common websites is built almost entirely on JavaScript, including Google, Facebook, Twitter, and Wikipedia. Web-Base











Framework

Bootstrap is one of the easiest framework to use, it has new version now Bootstrap 5!


Bootstrap is a powerful front-end framework for faster and easier web development. It includes HTML and CSS based design templates for creating common user interface components like forms, buttons, navigations, dropdowns, alerts, modals, tabs, accordions, carousels, tooltips, and so on. Bootstrap gives you ability to create flexible and responsive web layouts with much less efforts. Bootstrap was originally created by a designer and a developer at Twitter in mid-2010. Before being an open-sourced framework, Bootstrap was known as Twitter Blueprint. You can save a lot of time and effort with Bootstrap. So bookmark this website and continue on.

Bootstrap Framework help, what does it do?


Bootstrap’s form controls expand on our Rebooted form styles with classes. Use these classes to opt into their customized displays for a more consistent rendering across browsers and devices. Be sure to use an appropriate type attribute on all inputs (e.g., email for email address or number for numerical information) to take advantage of newer input controls like email verification, number selection, and more. Here’s a quick example to demonstrate Bootstrap’s form styles. Keep reading for documentation on required classes, form layout, and jaun.
