Over the years, the complexity of web applications has grown greater. For this reason the use of frameworks has become a key point in the speeding up and simplification of the development process. In this webinar we will analyze the main elements of comparison between two frameworks for the creation of Single Page Applications (SPA): Angular and React. Angular speeds up the development phase thanks to the Model View Controller (MVC) and Typescript paradigm, as a superset of JavaScript, guaranteeing maintainability and robustness of the software thanks to standards and naming conventions. React speeds up the application at runtime due to the way it manages the Virtual DOM, in terms of speed in modifying components without reloading the page.
