Erroneous output for single argument arrow function returning a function

[maarten-t]

The output for the case below is [''] where it should be ['a'].

const functionArguments = require('function-arguments');
functionArguments(a => function (){}); // -> [''] but should be ['a']

Yea, maybe. This package may not have full support as expected. It is just lightweight alternative to https://github.com/tunnckoCore/parse-function, try some of its versions.

But can you try this one

const functionArguments = require('function-arguments');
functionArguments(a => {});

because the tests use that and they are passing. But in anyway.. it's normal this is regex. :D

Oooh, i see why it is not working properly - showing that ['']... It is because we relay on the .indexOf to detect where are the opening and closing parens.

I think we can do a fix for such easy case.
