`_.where` function on array using JavaScript Library underscore.js ( #shorts )

Hi Friends,

`_.where` function on array using JavaScript Library underscore.js

`_.where` is a utility function in Underscore.js library that allows you to filter a collection based on multiple key-value pairs. It returns an array of all objects from the collection that match the specified properties.

In below example, we have an array of user objects users. We use _.where to filter the collection and retrieve all objects that have the property city set to "London". The result, filteredUsers, is an array containing the user objects that match the specified key-value pair.

Note: _.where returns an array containing all objects from the collection that match the specified key-value pairs.

// syntax
_.where(list, properties)

// example
var users = [
{ name: "Alice", age: 25, city: "New York" },
{ name: "Bob", age: 30, city: "London" },
{ name: "Charlie", age: 20, city: "Paris" },
{ name: "David", age: 35, city: "London" }
];

var filteredUsers = _.where(users, { city: "London" });

console.log(filteredUsers);
// [{ name: "Bob", age: 30, city: "London" },
// { name: "David", age: 35, city: "London" }]
