Background
Internet Explorer 11 and later includes new features and changes to existing features for improved standards compliance and interoperability with other web browsers. However, many existing JavaScript frameworks contain functionality that depends on functionality in earlier versions of Internet Explorer. As a result, parts of many popular JavaScript frameworks might not work correctly in Internet Explorer 11 or later Standards mode. Most of these frameworks have already been updated to work correctly in Internet Explorer 11 or later, but many web applications are still using earlier versions of incompatible frameworks.
Resolution
A framework compatible with the desired browser version should be delivered by its manufacturer. Where this is not feasible, Internet Explorer 11 Compatibility View should be used. It can be triggered by using the meta attribute value X-UA-Compatible.
