How to train a model in nodejs tensorflow js

Question

I'd like to create an image classifier, however I'm not familiar with Python. I'm familiar with javascript, which Tensorflow.js uses. Can it be used to train models, and how would it work? Sincerely, I don't know where to begin.

The only thing I figured out was how to use "mobilenet," which is ostensibly a collection of models that have already been trained, to import images and classify them:

const tf = require('@tensorflow/tfjs'),
      mobilenet = require('@tensorflow-models/mobilenet'),
      tfnode = require('@tensorflow/tfjs-node'),
      fs = require('fs-extra');

const imageBuffer = await fs.readFile(......),
      tfimage = tfnode.node.decodeImage(imageBuffer),
      mobilenetModel = await mobilenet.load();  

const results = await mobilenetModel.classify(tfimage);

which works, but it's no use to me because I want to train my own model using my images with labels that I create.

=======================

Say I have a bunch of images and labels. How do I use them to train a model?

const myData = JSON.parse(await fs.readFile('files.json'));

for(const data of myData){
  const image = await fs.readFile(data.imagePath),
        labels = data.labels;

  // how to train, where to pass image and labels ?

}
