How to get current record id in the Salesforce lightning component?

Getting current record id in lightning web component(lwc) is very easy.
If a component with a recordId property is used on a Lightning record page, the page sets the property to the ID of the current record. In the component’s JavaScript class, use the @api decorator to create a public recordId property. Here is example of javascript class.

import { LightningElement, api } from 'lwc';
export default class LWCExample extends LightningElement {
@api recordId;
}
To get current record id in lightning component(aura component), we had to implement force:hasRecordId to get record id in lightning aura component. But in lightning we component its very simple, we only need to use recordId property with @api decorator.

With the help of "hasRecordId" .
