How can I use Lodash to filter arrays?

How can I use Lodash to filter arrays?

You can use the _.filter method in Lodash to filter arrays based on a condition. For example, _.filter(array, predicate).

Can you show me an example of filtering an array of objects?

Sure! If you have an array of objects like [{ 'user': 'barney', 'active': true }, { 'user': 'fred', 'active': false }], you can filter active users with _.filter(users, { 'active': true }).

What if I want to filter based on a custom function?

You can pass a custom function as the predicate. For example, _.filter(users, user => user.user.startsWith('b')) will filter users whose names start with 'b'.

Is there a way to chain filters with Lodash?

Yes! You can use _.chain to create a chain of operations. For example, _.chain(users).filter('active').map('user').value() will give you an array of active user names.
