What happened to pluck() in lodash version 4? What is a suitable replacement?
This syntax _.pluck(users, 'firstName'); is simple to me. Seems that _.map(users, function(user) { return user.firstName; } would do the trick but it's not nearly as neat.

Overview. The _. get() method in Lodash retrieves the object's value at a specific path. If the value is not present at the object's specific path, it will be resolved as undefined . This method will return the default value if specified in such a case.
Lodash has the uniq method to return unique values from an array of objects. We call map to return an array of age values from array . And then we call uniq on the returned array to get the unique values from that returned array. So we get the same result for uniques as the other examples.
Lodash helps in working with arrays, strings, objects, numbers, etc. The _. pick() method is used to return a copy of the object that is composed of the picked object properties.
isUndefined() method is used to find whether the given value is undefined or not. It returns True if the given value is undefined. Otherwise, it returns false.
Looks like _.map(users, 'firstName'); should cover it.
