Function cannot be used outside of evalString

Javascript, NodeJS,

problem

Functions created in evalString cannot be used in the javascript context

repro

const { evalString } = require('@borkdude/sci');
var myFN = evalString("(fn [a] (+ a 10))")
myFN(4)

Gives

myFN(4)
      ^
TypeError: myFN is not a function

expected behavior

evalString should return a function that can be used from the javascript context. Like in the CLJ version:

(let [f (sci/eval-string "(fn [a] (+ a 10))")]
  (f 4))

Code above returns 14

[jeroenvandijk]

The function can be retrieved by accessing fields of the returned value. E.g.

 var f = evalString("(clj->js (fn [a b] (+ a b)))")
  console.log(f.s(1, 2))

I'm wondering if this is because of the metadata that is added: https://github.com/borkdude/sci/blob/c2ffce590f8185b9fd5fdbb7e3746ba37f2ae02f/src/sci/impl/fns.cljc#L84 For all none macro fn's this is not needed I think

@jeroenvandijk

const { evalString, toJS } = require('@borkdude/sci');

and then call toJS to the function, this will remove the metadata.

I'll check if non-macro functions work correctly without metadata and then publish a new release.

Fixed in npm version 0.0.13-alpha.5
