Way to display data using JavaScript

JavaScript can display data in different ways:

  • Using innerHTML
  • Using document.write()
  • Using window.alert()
  • Using console.log()

Using innerHTML

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.

Example :

 <!DOCTYPE html>
<html>
<body>

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

<script>
document.getElementById("demo").innerHTML = 'Hello World';
</script>

</body>
</html>
Output

Hello World

Using document.write()

You can use document.write() for testing purposes.

Example :

<!DOCTYPE html>
<html>
<body>

<script>
document.write('Hello World');
</script>

</body>
</html>

Using console.log()

Using console.log() you can see the data in browser console. This method is used for mostly debugging purposes.

Example :

 <!DOCTYPE html>
<html>
<body>

<script>
console.log('Hello World');
</script>

</body>
</html>
