LINQ Query Operations vs List<T> methods.

Many important methods in List<T> mutate the list

The similar LINQ query operations are pure functions - they return a new modified copy of the list

Traversal of collections
- List<T>: list.ForEach(Action);
- LINQ: newList = list.Select(Func);

Removal form collections
- List<T>: list.RemoveAll(Predicate);
- LINQ: newList = list.Where(negated Predicate);

Appending collections
- List<T>: list.AddRange(otherList);
- LINQ: newList = list.Concat(otherList);

Reversing collections
- List<T>: list.Reverse();
- LINQ: newList = list.Reverse();

Sorting collections
- List<T>: list.Sort(comparerMethod);
- LINQ: sortedList = list.OrderBy(KeySelector);
