Approach 7: Using Array.filter() and Object.keys()

Utilizing Array.filter() along with Object.entries() provides a concise method of filtering objects based on multiple properties. We are filtering the elements of the array based on the given condition and by the use of the Object.entries we are adding the filtered elements into it.

Example: This example shows the use of Array.filter() and Object.entries() method for filtering the array and adding element to to the object.

JavaScript

const data = [
    { id: 1, name: 'John', age: 25 },
    { id: 2, name: 'Jane', age: 30 },
    { id: 3, name: 'Doe', age: 25 },
];
 
// Filtering based on multiple properties
// using Array.filter() and Object.entries()
const filterConditions = { age: 25, name: 'John' };
const filteredData = data.filter(item =>
    Object.entries(filterConditions)
        .every(([key, value]) => item[key] === value)
);
console.log(filteredData);

Output

[ { id: 1, name: 'John', age: 25 } ]
