Module development and code questions

I'm confused on where to install 'js' files in Drupal 8. There always seems to be an interpretation issue on location over the years.

in the docs for the module I'm installing - they are saying

'site/all/libraries/abc-js-program/abc.min.js' but I'm thinking those are D7 install instructions?

and I'm not sure when I should forget possible outdated install docs and install as

'/modules/libraries/abc-js-program/abc.min.js'?

thanks,

Jeff

I'm using Ajax in a hook_form_alter function with custom user fields. I successfully did this in Drupal 7 but I can't get it to work in Drupal 8. What do I specify for the "wrapper"? What I'm doing is not working. Here's my code: (Everything works except the target HTML is not being replaced with the field_office element)

Hello,

I am learning Drupal 8 and its really confusing. Can any suggest me  the contributed modules that are easy to understand  Drupal coding standards, API's, theming  etc.

Hi Friends,

I am using Drupal commerce. For reports I found this module https://www.drupal.org/project/commerce_reports

From that module I am only able to view 'Purchased Item report' & 'Sales'

I am looking for reports related to promotions, user and store wise orders. On dashboard charts as well.

Is there any module which gives results store wise. Top 5 purchased customer store wise. How much stock is left product wise.

Thanks

I have successfully instantiated a relatively simple Drupal.behaviors function in my custom module which modifies an existing node_form. Now the second part is to use a $form element as a trigger for an action to dynamically populate a form field if desired. This value is generated in my hook_form_alter and set to drupalSettings.
