Solution

Reason for the Issue

Javascript files are cached, by default, for performance. Normally, in a production env, these files aren’t constantly changing, so this is perfectly acceptable. Your development machine would be acting this way as well, so you need to work around it. SO post on how JS files are cached


Solution:

In my experience, it is browser cache that causes this and, ritualistically, we just clear the cache before we run the site. So, in this order:

Change javascript

Save all

ctrl+shift+f5 in Visual Studio

When browser opens, hit f12, the ctrl+r (clear cache) and click yes

When cache clears, hit reload on page.

If above solutions are does not working, then please restart the visual studio
