JavaScript Number Pattern 1
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=5; i>=1; i--)
{
for(j=1; j<=i; 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
12345 1234 123 12 1
🧠 How the Program Works
Let's break down the logic behind the code:
- <!DOCTYPE html> and <html>: These lines define the document type and the start of the HTML code.
- <body>: The <body> tag indicates the beginning of the HTML body, where the visible content of the webpage is placed.
- <script>: This tag is used to include JavaScript code within the HTML document.
- var i, j;: Two variables i and j are declared using the var keyword. These variables will be used for controlling the loops and generating the pattern.
- for(i=5; i>=1; i--): This is an outer for loop that initializes i to 5, checks if i is greater than or equal to 1, and decrements i by 1 in each iteration. This loop controls the number of rows in the pattern.
- Inside the outer loop, there's an inner for loop:
- for(j=1; j<=i; j++): This inner loop initializes j to 1, checks if j is less than or equal to the current value of i, and increments j by 1 in each iteration. This loop generates the numbers within each row of the pattern.
- Inside the inner loop:
- document.write(j);: This line writes the value of j to the webpage. Since the inner loop generates numbers from 1 to the current value of i, this will output a sequence of numbers within the current row.
- document.write("<br>");: After the inner loop finishes, this line writes a line break (<br>) to the webpage. This creates a new line, separating each row of the pattern.
- </script>: Closes the JavaScript code block.
- </body> and </html>: Close the <body> and <html> tags, respectively, marking the end of the HTML content.
💯 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.

If you have any doubts regarding this article (JavaScript Number Pattern 1) please comment here. I will help you immediately.
Using JavaScript, I can’t seem to break out of an inner “for loop”. When the condition is met, then it breaks out of both the inner “for loop” and the outer “for loop”, so it does not find all the array items from the outer “for loop”. I tried using a break label, but it is ignored. Is there a better way to find all items from the 1st array in the 2nd array than a nested “for loop”?
