javascript - How to filter an object with its values in ES6

Question

What is the best way to filter an object this way in ES6?

Starting data:

const acceptedValues = ["value1","value3"]
const myObject = {
    prop1:"value1",
    prop2:"value2",
    prop3:"value3"
}

Expected output:

filteredObject = {
    prop1:"value1",
    prop3:"value3"
}

Answer 1

You can use reduce() to create new object and includes() to check if value of object exists in array.

const acceptedValues = ["value1", "value3"]
const myObject = {
  prop1: "value1",
  prop2: "value2",
  prop3: "value3"
}

var filteredObject = Object.keys(myObject).reduce(function(r, e) {
  if (acceptedValues.includes(myObject[e])) r[e] = myObject[e]
  return r;
}, {})

console.log(filteredObject)
