Notes

JavaScript can "display" data in different ways:

To access an HTML element, JavaScript can use the document.getElementById(id) method.

The id attribute defines the HTML element. The innerHTML property defines the HTML content:

<p id="demo"></p>

<script>
document.getElementById("demo").innerHTML ='JavaScript for Salesforce;
</script>

OUTPUT:

JavaScript for Salesforce

document.write():

<script>
document.write(2 + 3);
</script>

OUTPUT:

alert():

You can use an alert box to display data:

<script>
alert(2 + 3);
</script>

window.alert():

For debugging purposes, you can call the console.log() method in the browser to display data.

<script>
console.log(2 + 3);
</script>
