Does putting scripts on the bottom of a web page speed up page load?

Question

Yahoo best practices states that putting JavaScript files on bottom might make your pages load faster. What is the experience with this? What are the side effects, if any? <

Answer 1

There are some points.

1. It loads page fast since the JavaScript internal or external is on bottom.

2. If you have not used a onLoad method of window in JavaScript it will start execution as soon as it rendered. The Script at bottom ensures that your script will execute after page load.

3. If script is as a file means external then will render after the HTML image and other visual object that forms the page view.
