Q:

Is using a lot of AngularJS and JavaScript a bad practice for a website?

I am developing a huge project. The project is a webshop where most of the things are dynamically. Because of this, I decided to use AngularJS as a framework and added the jQuery library.
However, after developing more than 3 months now. I see that i got alot of AngularJS code.
My angular structure is currently:

34 controllers - All about 6kb in size (non-minified, I can still save some space there)*
1 file with more then 21 angular services.  - 11KB in size (non-minified)
1 file with 44 custom angular filters - 24KB in size (non-minified)
1 file with 32 custom angular directives - 18KB in size (non-minified)

On top of this i also use:

LESS
Bootstrap
jQuery
Typo.js**
Tablesaw

I did not  list every AngularJS or jQuery / JavaScript library I included inside the project. That would get a pretty long list, which would be unnessecary.

*Not all controllers are loaded at once. Most controllers at one time is 5.
  **When a word is misspelled it shows a word correction. Just like google.com. Also generates suggestions when a user searches for
  something and no results were found. It shows equivalent word
  suggestions that have results.

The project makes alot of AJAX calls using the $http service from AngularJS. Eg; auto complete in the search, pages, user information, basket data .. and much more.
The benefit of it in my eyes: 'It feels very smooth'. All data gets loaded within the same page if it is part of the same page.
For example:
The webshop articles are loaded on the page /assortment/. When searching, the search results are displayed on the same page, instead of redirecting to a /search/ page.
My question is:
Is using so much JavaScript a bad practice? Does this affect slower computers alot? or is the difference not noticable? Or do i have to improve the code, so it won't affect slower PC's?
I go to mention that I am not able to test it on different computers yet. So i do not know how it performs on other PC's.
I found 1 topic on SO with a similair question: What's the downside of using too much JavaScript?
But the question itself is more directing to; 'using libraries'

A:

It's 2017. There is no such thing as too much JavaScript. Maybe if someone is trying to access your site from a device that came out in the early 2000s, then they should rather get a new device.
We have the technology, so let's use it.
