[copied from GT FB group]

Is there a way to remove from a collection?

like thing.add(otherthing)

Essentially I want to move things from list2 to list2 incrementally.


>> things.shuffle
>> otherthings.add(things[1])
>> things.remove(1)

You can use the new functions .erase and .remove.

.erase removes something at a given index, for example:

>>friends = ["Liz", "Ana", "Sam"]

The code above will remove the second element from the collection (the one with value "Ana")

.remove will remove all of the elements that match a give value:

>>tripsThisYear = ["Paris", "London", "Rome", "London", "Madrid"]

If you run the code above you will see that the function removes the two elements with value "London"
