How to useArray.from() and filter() in Javascript

Q: How to useArray.from() and filter() in Javascript

A traditional for loop allows explicit control over the filtering process, iterating through each object and applying the specified conditions. we will be using the for loop and by using if else we will check for the condition and add the true values into the newly formed array.

Approach 2: Using a for Loop

Approach 4: Using reduce() method

The combination of Array.from() and filter() allows for a concise method of filtering based on multiple properties. we will filter the array by the use of the filter() method and then we will make an array of those values by the use of the Array.from() method.

Example: This example shows the use of the above approach.

JavaScript

// Sample array of objects
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.from() and filter()
const filteredData = Array.from(data).filter(item =>
    item.age === 25 && item.name === 'John');
console.log(filteredData);

Output

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