Refs in React
From Logic Wiki
Refs are used to access DOM elements
On top of the file create a ref first
username = React.createRef();
Then assign it to a form element
<input ref={this.username} is="username" type="text">
and use it like
const username = this.username.current.value;
it can be used to create a focus for example
componentDidMount(){
this.username.current.focus();
}
of course we can just use autoFocus attribute instead.
