Discussions about rest operator

rest operator

const { someKey, ...rest } = someObject
<div>rest.someValue</div>

Technically the current implementation of rest is 99% implementation of spread, but I am not sure it is the best way. Probably a small and specific proxy is better

const spread = {
  ...object1,
  ...object2,
} 
// ->
const spread = proxyObjectSpread(object1, object2);
// ------
cosnt proxyObjectSpread = (...objects) => {
  const assingIndex = (object, x) => Object.keys(object).reduce((acc, key) => {acc[key]=x;return acc;},{});
  // create "shape" objects, with values === used used object id
  const spreadKeyHolder = Object.assign({},...(objects.map(assingIndex));
  return new Proxy(spreadKeyHolder, {
    get(key) {
       return objects[spreadKeyHolder[key]][key]; // redirect read
    }
 })
}

PS: You are 100% right.

the current implementation would convert array to the object 🤷‍♂️
