The end of Internet Explorer has been a long time coming Microsoft ended support for Internet Explorer 11 for the Microsoft Teams web app As a little ironic joke, I made sure that this little app wouldn't work in ie11 by using es6 arrow functions, let and const But IE11 does support let and const 😉 Anyway, I was already aware that Microsoft had to support IE until the end of support of Windows 10 I wish they didn't, as they themselves consider it a dead browser If the Internet Explorer 11 stops working or doesn't responding for a long time, and you can't close it, you can force to close it via Task Manager You can press Ctrl Shift Esc to open Task Manager window Under Process tab, you can find Internet Explorer 11 process, and rightclick it to select End task
