@ViewChild/@ViewChildren decorator provides us with a easy and simple way to access and manipulate the properties and methods of a Child Component from a container or root component.

By using @viewchild we can achieve the following things,
• Accessing template of same component
• Accessing the template of child component

The @ViewChild query returns the first matching element from the DOM and updates the component variable on which we apply it.
we must supply the query selector, which can be a string or a type as the first argument to the ViewChild
