Hi Lukesh,

@track: To track a private property’s value and rerender a component when it changes, decorate the property with @track. Tracked properties are also called private reactive properties.

Fields are reactive. If a field’s value changes and the field is used in a template or in a getter of a property that’s used in a template, the component rerenders and displays the new value.
There is one use case for @track. When a field contains an object or an array, there’s a limit to the depth of changes that are tracked. To tell the framework to observe changes to the properties of an object or to the elements of an array, decorate the field with @track
