JavaScript: Tips of the Day

Creates an object composed of the properties the given function returns truthy for. The function is invoked with two arguments: (value, key)

Example:

const tips_composed = (obj, fn) =>
  Object.keys(obj)
    .filter(k => fn(obj[k], k))
    .reduce((acc, key) => ((acc[key] = obj[key]), acc), {});

console.log(tips_composed({ p: 2, q: '4', r: 6 }, x => typeof x === 'number'));

Output:

[object Object] {
  p: 2,
  r: 6
}
