How an angular application renders on web browser.

As angular is a framework where we write code in typescript. Angular is a component based framework where we create UI's using components. Angular application does not directly run on browser as it does not contain js files in it and Browser only understands JavaScript files to render information.

For that we use a command to create JavaScript bundle of our angular application and then it can be rendered. The process of changing our angular application from typescript modules to JavaScript bundle is called transpiling.
