In this article, we would like to show you how to filter an array using multiple conditions in JavaScript.

Practical example

Edit

In this example, we create an object containing conditions, then we use it to filter users array. The filter() method goes through all the keys in the users array returning only the objects that match the criteria.

xxxxxxxxxx
 
const conditions = {
    name: 'Tom',
    age: 25
};
​
const users = [
    { id: 1, name: 'Tom', age: 25 },
    { id: 2, name: 'Tom', age: 25 },
    { id: 3, name: 'Tom', age: 30 }
];
​
const result = users.filter((object) => {
    for (const key in conditions) {
        if (key in object && object[key] !== conditions[key]) return false;
    }
    return true;
});
​
console.log(JSON.stringify(result, null, 4));
