Calculations are usually performed by a script, but the output element provides semantic meaning to the calculation results. The HTML5 keygen element is used to generate a key pair to add security in an HTML form. The HTML5 datalist element provides pre-defined options that sort and autocomplete themselves as users type into the field. The input element generates various form field types, depending on the attribute specified with it.

Sarah has written several JavaScript scripts for her Web site, but she realizes that implementing the scripts may be complicated by the fact that people may view her pages using different user agents and user agent versions. What should Sarah do to ensure that her scripts will run correctly without knowing what user agent a person will use to view her pages? - Correct answer-Test her scripts in the latest versions of popular browsers. Because JavaScript programs are typically designed to run within HTML documents, they are not tied to any specific hardware platform or operating system. However, JavaScript programs are tied to a specific user agent. Generally, these user agents are browsers. Each user agent tends to implement JavaScript differently. Different vendors and user agent versions can complicate your JavaScript implementation. Because you usually cannot guarantee that a user will access your JavaScript code using a specific user agent, take care to create code that will run on as many platforms as possible. At a minimum, you should test your scripts in the latest versions of Internet Explorer, Firefox, Chrome and Safari.

When validating your markup code, sometimes one small flaw can cause the remaining code on the page to fail validation, even if the remaining code is actually valid. Sometimes when a validation program finds a problem, it does not report the correct cause or it may not report the cause clearly.
