React JS became available to developers earlier: Facebook released it for mass use in 2013. Angular is a Google product and went public in 2016. Developers had more time to get used to React and to make convenient improvements to the product. However, Angular is quickly catching up and the demand for it will undoubtedly increase in the coming years.

React is used by AirBnb, Dropbox, Facebook, Instagram, Netflix, WhatsApp, and Uber. Angular's clients include CVS shop, Delta, Eat24, Google Express, NBA, onefootball.

Angular (MVC framework) is software that allows you to assemble a project from separate modules and components. React is an open-source front-end library for integration, with a significant number of packages. Data binding in React is done in one direction, in Angular in two directions. React is based on JSX + JS (ES5 / ES6), Angular is built on HTML and TypeScript.

React uses a dynamically typed language, Angular a statically typed one. Dynamically typed languages are easier to learn, less time-consuming to write, flexible, and more creative to developers. JavaScript (ES6), on which React is built, has been the mainstream programming language since 1995. It contains convenient modules, classes, literals, and spread operators inside it, the structure of the code is extremely clean.

TypeScript, which Angular is based on, entered mainstream use in 2012 and does not rely on a class system. If a person has previously worked only in dynamically typed programming languages, it will be difficult for him to master statically typed TypeScript. When attracting new developers to the project, you will have to put in additional time for their training.
