Why is this bad?

const something = (params) => value;

TL;DR Because this ISN'T bad

function (params) {
    return { value: value };
}

This looks like those 👇

(params) => { value }

All of these are the same

(params) => { value: value }

(params) => {
  value: value
}

(params) => {
  value:
    return value
}

But the first is this

(params) => {
  return value
}

But what we wanted is this

(params) => {
  return { value: value };
}

So...

Never use arrow functions!
