I wanted to make an npm module via ReasonML

• a function need to accept objects
• but couldn't find a way to convert an JS Object to a Reason Record (holds optional value)

// I wanted to have an npm module function like below
reasonFnExposedToJs({key1: 'blah', key2: undefined})

// and works fine with Reason side but generated argsFromJs looks like below

const ttl = (strings, ...variables) => [strings, ...variables]
// or const ttl = (...args) => [...args]

// we are using www.styled-components.com as an example

const Adder = ({className, x, y}) => {
  return (
    <span className={className}> {x+y} </span>
  )
}

function printTo100(n) {
  for (i in [...Array(100).keys()]){
    console.log(`${n}-${i}`)
  }
  return Promise.resolve()
}

Promise.all(
  printTo100('a'),
  printTo100('b'),
