I am trying to create a neural network using javascript. So, I found brain JS, and I'm following this tutorial.

https://github.com/BrainJS/brain.js#brainjs

First of all, the installation : npm install brain.js But I got warnings

npm WARN deprecated uuid@3.4.0: Please upgrade and errors

npm ERR! path /home/khouloud/node_modules/gl
npm ERR! command failed
npm ERR! command sh -c /tmp/install657645639957.sh

I sow in the internet that these are just warnings and I can skip them

So I use visual studio and I try this code line

const brain = require('brain.js');

I got this Uncaught ReferenceError ReferenceError: brain is not defined

I don't know what is the source of the problem Someone help me !
