frontend JS- browser compatibility

[mattlub]

it seems you are avoiding certain JS features on the front-end, like const or arrow functions, but you use the fetch api which is less supported than these other features.

I would either convert all your code to ES6 or look into a polyfill for fetch.

Let me know if you have any questions.
