JavaScript Number Pattern 34

Here`s a program that prints the above number pattern using JavaScript Programming:

example.html

Copied

<!DOCTYPE html>
<html>
<body>

<script>
var i, j;
for(i=0; i<=5; i++)
{
 for(j=0; j<=i; j++)
  document.write(i+j +" ");
 document.write("<br>");
}
</script>
</body>
</html>

💻 Testing the Program

When you run the above program, it will print the following output:

Output

0 
1 2 
2 3 4 
3 4 5 6 
4 5 6 7 8 
5 6 7 8 9 10

🧠 How the Program Works

Let's break down the logic behind the code:

<script>: This tag indicates the start of a JavaScript code block within an HTML document.
var i, j;: Declares two variables, i and j, which will be used as loop counters.
for(i=0; i<=5; i++): This is an outer loop that initializes the value of i to 0 and increments it by 1 in each iteration until i is no longer less than or equal to 5.
{: The opening curly brace denotes the start of the code block associated with the outer loop.
for(j=0; j<=i; j++): This is an inner loop that initializes the value of j to 0 and increments it by 1 in each iteration until j is no longer less than or equal to i.
{: The opening curly brace denotes the start of the code block associated with the inner loop.
document.write(i+j +" ");: This line writes the sum of i and j, followed by a space, to the document. The document.write() method is used to output content to the HTML document.
}: The closing curly brace denotes the end of the code block associated with the inner loop.
document.write("<br>");: This line writes a line break (HTML <br>) to the document, creating a new line after each inner loop iteration.
}: The closing curly brace denotes the end of the code block associated with the outer loop.
</script>: This tag indicates the end of the JavaScript code block.

💯 Tips for Enhancement:

Explore the versatility of this pattern by adjusting its parameters. Whether you increase or decrease the size, tweak the spacing, or modify the characters used, each change opens up a world of possibilities, allowing you to customize and create your unique visual effects.
