How does lodash.matchesProperty work?

lodash.matchesProperty creates a function that compares the value of a given property of an object to a given value and returns true if they match.

const users = [
  { id: 1, name: "Alice", isActive: true },
  { id: 2, name: "Bob", isActive: false },
  { id: 3, name: "Charlie", isActive: true },
];

const isActiveUser = _.matchesProperty("isActive", true);

const activeUsers = users.filter(isActiveUser);

console.log(activeUsers); // [{ id: 1, name: 'Alice', isActive: true }, { id: 3, name: 'Charlie', isActive: true }]

In the example above, lodash.matchesProperty is used to create a predicate function called isActiveUser that matches an object based on the isActive key having a value of true. This function is then used with the Array.filter() method to filter out only the active users from the users array.
