Posts like these should be considered click bait. If you are using a library then technically it's not you writing from scratch.

Unless you are writing vanilla JavaScript without calling other libraries, all you are doing is importing other code.

So in your count, perhaps include the number of lines of the library that is actually doing the work.

Indeed, create a neural network in only two lines:

  import * as nn from 'neural-network'  
  nn.create()

Well, of course you can create a neural network in Javascript in only 30 lines of code if you use a library!

I learned backpropagation through understanding how computational graph works. Though you need a little bit of differential calculus. But it's not that hard though.
