The script does not work in internet explorer

[xaozai]

This script does not work in Internet Explorer [which is installed by default in Windows Server 2019].
It does not work because it uses MS-reserved names, such as default, catch, finally, return etc.
For example: Object.prototype.hasOwnProperty.call(g,"default")?g.default, return:function(){jo=!0}};, if(!wk.catch||!wk.finally)return!0;.
All such names should be framed with single quotes.

All these errors are displayed in the developer Tools console built into IE.
