Where to place the bootstrap and javascript files

Hello!
I am trying to do the web interface exercise on my laptop too, for that i download the bootstrap.min.js, vue.min.js and roslib.min.js files. I want to know should i place these files in some specific folder like /opt/ros/kinetic/share…or these can be placed anywhere in system.
Thanks

In theory you can place them wherever you like but the references to the JS files in the html file must be correct.

I advise you place them in your workspace so that you can easily reference them. Create a folder structure similar to what we have in the course and place the JS files as they were placed in the course.
