Why is slice called with `[1]` instead of `1`?

[cdeutsch]

This isn't an issue, just trying to understand the code (and JS for that matter).

Why is this line called with [1] instead of 1?

react-fetch-hook/usePromise.js

Line 8 in 67223d7

var inputs = Array.prototype.slice.call(arguments, [1])

Is it handling some edge case? Didn't have luck Googling it. Thanks
