Filter object using ES6

Scenario:

Assume we have the following object

ingredients = { 'pizza': false, 'basil': true, 'olives': false }

Requirement:

Filter object based on its values using ES6/JS. We need to get the filter the above object which has value set to true.

Solution:

The object can be filtered using filter and map functions.

let filteredIngredients = Object.keys(ingredients)
              .filter((value) => {
                  return ingredients[value] == true;
}).map((ingredient, index) => {
    return ingredient;
              });

console.log(filteredIngredients);

Output:

["pizza", "basil"]
