multiFilter.js

/**
 * Multi-filter an array of objects
 * @param  {Array}  array  : list of elements to apply a multiple criteria filter
 * @param  {Object} filters: Contains multiple criteria filters by the property names of the objects to filter
 * @return {Array}
 */
function multiFilter(array, filters) {
  let filterKeys = Object.keys(filters);
  // filters all elements passing the criteria
  return array.filter((item) => filterKeys.every((key) => (filters[key].indexOf(item[key]) !== -1)));
}

test.js

let products = [
  { name: "A", color: "Blue", size: 50 },
  { name: "B", color: "Blue", size: 60 },
  { name: "C", color: "Black", size: 70 }
];

let filters = {
  color: ["Blue", "Black"],
  size: [70, 50]
};

// expected
let expected = [
  { name: "A", color: "Blue", "size": 50 },
  { name: "C", color: "Black", "size": 70 }
];

var filtered = multiFilter(products, filters);

console.info('Expected');
console.log(expected);
console.info('Filtered');
console.log(filtered);

🚀 Also via Git, you can update your fork with the original, e.g.

2. Go to your forked directory
3. Add upstream with the original gist:
   git remote add upstream git@gist.github.com:f11d669ba286f21b7a2dcff69621eb72.git
4. Sync with the upstream:
   git fetch upstream
5. Reset your master with the upstream and push it to server:
   git reset --hard upstream/master && git push -f origin master
6. Or, if you have custom changes, you can rebase it and push it to server:
   git rebase upstream/master && git push -f origin master
