Quickest and best way to determine Angular/AngularJS version a site is using? : <p>At work, I've inherited over 30 web sites/applications built using C#, ASP.NET, MVC and AngularJS/Angular. The sites were built and updated between 2010 and 2018. Some have been built and updated more recently than others. What is the quickest and best way to determine decisively what version of AngularJS or Angular each site is using?</p>

<p>For the record, I don't have any Angular experience yet, other than a few modifications to some of these sites. My background is in C#, ASP.NET, MVC, React, JS, PHP, VB6 etc. The technologies and design decisions used for these sites were an interesting choice, which wasn't mine to make, so please don't get too excited about them. What I find will determine which version of Angular I will focus on learning initially.</p>
