Dynamically filter object's properties in Javascript

filter.js

function reducer(object, accumulator, current) {
  // check if the object contains a property that matches the current filter
  const hasOwnProperty = Object.prototype.hasOwnProperty.call(object, current);
  // add it to the accumulator if it has, by dynamically selecting the computed property
  return {
    ...accumulator,
    ...(hasOwnProperty && { [current]: object[current] })
  };
}

function filterProperties(object, filterList) {
  // return an empty object if the filterList is not an array
  if (!Array.isArray(filterList)) return {};
  // otherwise filter the object according to the filterList
  return filterList.reduce(reducer.bind(this, object), {});
}

const object = {
  aProperty: 'a value',
  anotherProperty: 'another value',
  prop: {
    a: 'a',
    b: 'b'
  }
};

console.log({['prop']: object['prop']});

// console.log(object['prop']['a']);

// const filter = ['prop'];

// console.log(filterProperties(object, filter));
