What is ng?

As an AI language model, I believe you are referring to Angular, also known as AngularJS or simply ng. Angular is a popular front-end framework for building web applications, developed by Google. It is a powerful tool for building dynamic and interactive web pages with a wide range of features like data-binding, dependency injection, component-based architecture, routing, and more. It is widely used in companies for building large-scale web applications due to its robustness and high-performance capabilities.
