setWith extraArgs

[alexesDev]

Hi. Why setWith not working?

setWith((_, x) => x, 'test', { test: 1 }, 2);
{ test: [Function: bound slice] }

Also

const fn: unchanged.withHandler = (value: any, preventUpdate: boolean): any =>
  preventUpdate ? currentValue : "quz";

console.log(setWith(fn, "foo[0].bar", object)); // {foo: [{bar: 'quz'}]}

Print

{ foo: [ { bar: 'baz' } ] }

This is a very strange code 😮

const slice = Function.prototype.bind.call(Function.prototype.bind, Array.prototype.slice);

Why not just Array.prototype.slice.call?

Ha okay so this is a stupid mistake on my part ... the first param of that setup should be Function.prototype.call, not Function.prototype.bind. Not sure why my testing didn't catch this, but I'll update.

To answer your question, it avoids property access. It's a micro-optimization that had a slight perf win in specific legacy environments.

This should be fixed in 2.2.1. Thanks for calling this out!

Also, I realized my ambiguous wording in my previous response could be misinterpreted (what I get for replying at 4:30AM). This was a totally valid issue, the stupid thing was my mistake, so apologies for the miscommunication.
