JavaScript Number Pattern 7

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=1; i<=5; i++)
{
 for(j=i; j>=1; j--)
  document.write(j);
 document.write("<br>");
}
</script>
</body>
</html>

💻 Testing the Program

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

Output

🧠 How the Program Works

Let's break down the logic behind the code:

var i, j;: This declares two variables i and j using the var keyword. These variables will be used as loop counters.
for(i=1; i<=5; i++): This is an outer loop that iterates from i being 1 to 5, incrementing i by 1 in each iteration.
The opening curly brace { marks the beginning of the code block associated with the outer loop.
for(j=i; j>=1; j--): This is an inner loop that iterates from j being equal to the current value of i down to 1, decrementing j by 1 in each iteration.
Inside the inner loop, document.write(j); is used to write the value of j to the HTML document. This will print the current value of j in each iteration of the inner loop.
After the inner loop completes, the outer loop does not immediately move to the next iteration. Instead, it proceeds to the next line within its block.
document.write("<br>");: This line writes an HTML line break (<br>) to the document. This will create a new line in the output, separating the sequences of numbers produced by the inner loop.
The closing curly brace } marks the end of the code block associated with the outer loop.
After the outer loop completes all iterations (from 1 to 5), the JavaScript program finishes executing.

💯 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.
