Microsoft edge being used in a web form 2010 app that uses javascript
In a vb.net 2010 web forms application, I have found that Internet Explorer 11 does not work any longer due to the obsolete statement of
"var firstVisibleElement = Array.from(document.querySelector("#rso").children) .find(positiveClientHeight)". The Array.from no longer works.
I ran the same application in Microsoft Edge and I found that the application runs correctly.
Thus since Internet Explorer 11 does not work due to deprecated and/or obsolete JavaScript statements, are there deprecated and/or obsolete features in Microsoft Edge?
If so, can you tell me and/or point me to link(s) url(s) that will tell me what the deprecated/obsolete javascript objects are?
If there is nothing deprecated/obsolete, would you let me know that also?
It seems that EDGE only runs the most modern standard of the web.
Microsoft Edge doesn't support ActiveX controls, Browser Helper Objects, VBScript, or other legacy technology.

But yes, Microsoft edge DOES have legacy support, but not out of the box.
If you have websites or web apps that still use this technology and need IE11, you can add them to the Enterprise Mode site list, using the Enterprise Mode Site List Manager.
Compatibility and security. Microsoft Edge lets you continue to use IE11 for sites that are on your corporate intranet or that are included on your Enterprise Mode Site List. You must use IE11 to run older, less secure technology, such as ActiveX controls.
