Excuse my ignorance but I only have experience in JS and not any other "advanced" or well-established programming langs, how's thin arrow syntax gonna fix this prob that fat arrow can't?
Fat arrow functions have lexical this: this inside the function is bound to what it was outside. Thin arrow functions have a dynamic this, determined by how they are called. Because the library relies on dynamic this as the place where the data is sent, fat arrow syntax isn't useful with it.
