In many cases, the built-in collection methods return an array instance that can be directly chained, but in some cases where the method mutates the collection, this isn’t possible. So, lodash comes in handy, as it will treat hash objects as if they were arrays already. javascript object ecmascript-6 lodash. They provide a group of tools used for common programming operations having a strong functional programming task.
