How to get input value in Angular?

Angular is a popular web development framework that allows developers to build dynamic, interactive web applications. One common task that developers often face is how to retrieve input values from user input fields. In this article, we will explore various techniques to get input values in Angular.

One of the most common ways to get input values in Angular is by using Two Way Data Binding. Two Way Data Binding allows you to bind the value of an input field to a variable in your component, so that any changes made to the input field are automatically reflected in the variable, and vice versa.

Another way to get input values in Angular is by using Template Reference Variables. Template Reference Variables allow you to reference an element in your template using a variable, and then access its value using that variable.
