Why do we place JavaScript code inside comment fields?

• Browsers that do not support JavaScript, will display JavaScript as page content.
• To prevent them from doing this, and as a part of the JavaScript standard, the HTML comment tag should be used to "hide" the JavaScript.
• Just add an HTML comment tag &lt!-- before the first JavaScript statement, and a --> (end of comment) after the last JavaScript statement.
• However, this is an optional, but considered good practice.
