A quick comparison between pure HTML and HTML with JavaScript can be seen from [[Editing_content_of_a_webpage_using_either_HTML_or_Script|this example]]. Essentially, the Browser produces a page structure by reading the HTML, and then the browser will run the JavaScript instructions as it meets them (or a call to the separate file containing that code) and that can be interpreted to modify what is seen on the web page. A user can normally ask their browser to see the original HTML (display source) and to display the script that is modifying that. The user may be able to stop the script from running or run a different script, so JavaScript can have security implications. It can however be an advantage that code can be run easily to update part of a page, leaving the rest. A disadvantage is that different browsers may offer different versions of JavaScript, so the page designer cannot make assumptions about what JavaScript code will be available to all potential users. | A quick comparison between pure HTML and HTML with JavaScript can be seen from [[Editing_content_of_a_webpage_using_either_HTML_or_Script|this example]].
