How does lodash.findWhere work?

lodash.findWhere is a method in the Lodash library that iterates over a collection of objects, returning the first object that matches all of the provided key-value pairs. It is similar to _.find, but takes an object of properties to match against, rather than a predicate function. In more detail, lodash.findWhere accepts two arguments: a collection to iterate over, and an object of key-value pairs to match against. It then iterates over the collection and returns the first object that matches all of the key-value pairs in the second argument. It uses _.matches to test each object for a match. If no matches are found, it returns undefined.

const users = [
  { name: "Alice", age: 25 },
  { name: "Bob", age: 30 },
  { name: "Charlie", age: 35 },
];

const result = _.findWhere(users, { name: "Bob" });
console.log(result);
// Output: { name: 'Bob', age: 30 }

In this example, we have an array of users objects. We then call _.findWhere with two arguments: the users array and an object representing the properties we want to search for. In this case, we are searching for the user with the name property set to 'Bob'. _.findWhere returns the first object in the users array that matches the search criteria, in this case the object with name: 'Bob' and age: 30.
