IE11 javascript2.0 invalid

With the launch of IE11, many website and application developers are already using the new JavaScript 2.0 language to improve application performance and security. However, many users have discovered that JavaScript 2.0 seems to be broken in their browser when using IE11. This article will explore the causes and solutions to this problem.

In IE11, there is indeed a problem with the implementation of JavaScript 2.0. This is because IE11 only supports the ES5 standard JavaScript language and does not support ES6 and above versions. This means that if your website or application uses ES6 and above versions of the JavaScript language, it will not run properly on the IE11 browser.

The failure of JavaScript 2.0 in IE11 may cause a series of problems in applications, such as code crashes, slowdowns, or loss of functionality. If you encounter these problems, then you need to make some adjustments to make your application work properly in IE11 browser.

First of all, you need to check whether the JavaScript language ES6 and above is used in your application. If so, you need to convert your code to ES5 standard. This can be done using many open source tools, such as Babel or TypeScript.

Secondly, you should use some tools to test how your application performs on different browsers. This includes using cross-browser compatibility testing tools to see if your app behaves consistently across different browsers, and using live browser tools to test your app's performance across different browsers.

Finally, you can consider using some plugins or frameworks to help you solve this problem. For example, you can use the ES5-Shim plugin to simulate features that are not yet implemented in the ES5 standard. Some popular front-end frameworks, such as React and AngularJS, also provide support for IE11.

In short, the failure of JavaScript 2.0 in IE11 is a challenge for many developers and users. However, with some tricks and tools, you can easily solve this problem and make your application work properly on IE11 browser.
