What is JavaScript? Introduced in 1995, it is now ranked as the most popular programming language of 2022, JavaScript has become the go-to language for most developers and engineers. The increasing popularity of this programming language has encouraged more companies to make use of this language. Why is JavaScript so popular? There are numerous reasons why JavaScript is so popular in recent years. The most important is the wide range of uses of this language and the flexibility of the language. It is also very useful as it can be used as a programming language for Front-end and Back-end. Due to the immense popularity of JavaScript, it has various frameworks. What are frameworks? A framework is an abstract written in any programming language which can then be modified according to the additional code written by the coder/developer. Angular and React JS is the most used frameworks of JavaScript. Angular Angular is a front-end framework that helps create single-page applications with ease. It is a JavaScript framework.Single-page applications are those that load the entire website on a single page. React Js React Js works by allowing you to build small and simple components and then merge them together to form UI.Now let us compare the two frameworks. Angular vs React JS : Programming language 1) Angular is based on the programming language TypeScript. TypeScript is JavaScript with additional features.2) React is based on the programming language JavaScript. Angular vs React JS : Learning Curve 1)Angular consists of various syntaxes which need to be learned. This means that the learning curve of Angular increases while learning these syntaxes which are only Angular specific.2)In the case of React Js, there is an additional component of TypeScript involved, which adds more structure. This indicates the increase in the learning curve for React Js. Angular vs React JS : Architecture 1)Angular comes with a lot of built-in features. Angular is a structural framework, which makes it easier to create different websites or apps.2)React Js comes with lesser built-in features3)React Js is a library, which is used by developers to create UI(User Interface) Angular vs React JS : Speed 1) React is proven to be faster as it uses DOM. React is built in small components, this causes it to reduce speed and increase performance.2) On the other hand, Angular is constantly improving its framework. Despite its complexity, it offers high performance. CONCLUSION: WHICH IS BETTER?: ANGULAR OR REACT JS Both frameworks are the top choices for many developers across the globe. If you are a new developer and wish to start your JavaScript journey, Angular may be a better choice. Despite angular having a being a complex framework, it offers structure. It is also the better choice in terms of speed for a beginner. If you are a more experienced developer React Js is the better choice for you. It is smaller in size. Experienced developers will find React Js to be faster.Angular is the better choice when it comes to big projects whereas React is the go-to framework for small projects.AngularJS vs. Backbone.js: Which One is Better Comparing Two Best JavaScript Frameworks?
