new_array = Select(array, ::delegate);

---

Foreach(<array>, <delegate>)

Executes a provided function for each array element.

Foreach(players, ::heal);

---

Aggregate(<initialValue>, <array>, <delegate>)

Aggregate the result of multiple delegate.

result = Aggregate(initialValue, array, ::delegate);

---

All(<array>, <predicate>)

Check if all items match the predicate.

isAll = All(array, ::predicate);

---

Where(<array>, <predicate>)

Reconstruct the array with only matches values from the predicate.

new_array = Where(array, ::predicate);

---

Any(<array>, <predicate>)

Check if atleast one item match the predicate.

isAny = Any(array, ::predicate);

---

Last(<array>, <predicate>)

Get the last item that match the predicate.

last = Last(array, ::predicate);

---

First(<array>, <predicate>)

Get the first item that match the predicate.

first = First(array, ::predicate);

---

Count(<array>, <predicate>)

Count all items that match the predicate.

count = Count(array, ::predicate);

---

Min(<array>)

Get the smallest value from an array of int/float/string/vector.

min = Min(array);

---

Max(<array>)

Get the biggest value from an array of int/float/string/vector.

max = Max(array);

---

Cast(<array>, <type>)

Reconstruct an array with all items casted to a specific type. Available types are: int, float, string.

strings = Cast(array, "string");
ints = Cast(array, "int");

---

OfType(<array>, <type>)

Reconstruct the array with only the specified type. Available types are: int, float, string.

strings = OfType(array, "string");
