Explanation

Let's break down the JavaScript code snippet:

document.getElementById("myTable"): This retrieves the table element with the specified ID (myTable).

getElementsByTagName('tbody')[0]: This gets the <tbody> element within the table, where we'll be appending our new rows.

insertRow(): This method adds a new row to the table.

insertCell(): This method inserts a new cell into a table row.

innerHTML: This property sets or returns the HTML content (inner HTML) of an element.

By combining these methods and properties, we can dynamically add rows to our HTML table whenever the addRow() function is called.

Conclusion

In this guide, you learned how to dynamically add rows to an HTML table using JavaScript. This functionality can be useful in a variety of web development scenarios, such as data entry forms, dynamic tables, and more. By leveraging JavaScript's DOM manipulation capabilities, you can enhance the interactivity of your web pages and provide a better user experience.
