Private reactive property and tooltip in lightning web component

lightning web components, lwc, @track lwc example, @api lwc, @wire lwc example, lwc basic example, lwc private reactive property
lwc private reactive property @track

In this above gif name field in the component will get re rendered whenever the value changes because of a property decorated with “@track”.

Tracked properties are also called private reactive properties.

whenever there is a need of using property decorated with @track”. import them in lwc module as below.. same applies for @api , @wire.

import { LightningElement, track } from 'lwc';

Following lwc is a simple example that displays a name field it will get re rendered whenever there is a change in its input field and i have used lwc helper text(tooltip) base component to display some custom info related to that field for better user experience.
