Extend the Array Prototype with a `compact()` Method

Extend the global Array object to have an instance method named compact() which returns a copy of the array without duplicate entries, and falsey values (with the exception of 0 and false).

Examples

[1, 2, 2, 3, 4, 4, 5].compact() ➞ [1, 2, 3, 4, 5]

[true, false, true, false].compact() ➞ [true, false]

[0, "hello", undefined, 17.2].compact() ➞ [0, "hello", 17.2]

[null, 0, undefined, 1, "h", "", 892].compact() ➞ [0, 1, "h", 892]

Notes

This does not need to consider / work with objects, arrays, or non-primitive types as entries. Bonus if it does though!
