Automatic Semicolon Insertion

What is Automatic Semicolon Insertion?
If we write some code and just gave enter, so It will be add automatic semicolon.

For that you need to create first html code.

HTML

<p id="demo1"></p>

After that add this JS code.

JS

function getPerson(){
    return
    {
        firstname: 'Tony'
    }
}

document.getElementById("demo1").innerHTML = getPerson();
