object-iterable/src/index.js

Create a new object containing the same properties (through assignment) of another object along with an @@iterator method can make use of the default iteration behavior (such as for-of) that built-in iterables like Array or Map have.

function objectIterator(obj) {

  const iterableObj = {

    [Symbol.iterator]: function() {
      const keys = Object.keys(this);
      let i = 0;

      return {
        next: () => ({
          value: this[keys[i++]],
          done: i > keys.length
        })
      };
    }

  };

  return Object.assign(iterableObj, obj);
}

module.exports = objectIterator;
