What is Angular JS

AngularJS is a JavaScript-based open-source front-end web framework created in 2009 by Google company employee Misko Hevery. Which was designed to solve the challenges faced in developing a single-page application. Here open source framework means that we do not need to take any permission from anyone to use AngularJS in our website nor do we have to pay any money to anyone in any way. We can also modify its source code and develop a new framework along with using AngularJS
