In your doSomething() static function, 'arr' is a local variable and therefore ceases to exist when doSomething() returns. Therefore the Array object that it points to becomes eligible for garbage collection.
If 'arr' were a static var, doSomething() should set it to null before returning if you want to make the Array object eligible for garbage collection. Otherwise the static var, which always exists, would continue to point to it and prevent the Array object from being GCd.

Only > dynamically defined properties can be deleted. The array isn't added dynamically - it's declared so you may not delete it. The storage allocated for the array will be eligible for garbage collection (provided nothing else is referencing the array) when you leave the function - it's no longer in scope. In other circumatsnces, you can make the array eligible for garbage collection by setting arr to null (provided nothing else is referencing the array).
