5 types of creational design patterns:

1. Factory Design Patterns: Purpose: Create Objects, Keep Object Creation Centralized
2. Abstract Factory Design Patterns
3. Singleton Design Pattern: Limit instantiation  of a clas to only one instance
4. Prototype Design Patterns: Object creation based on Prototype Object Instance; Simpler Object Creation than Factory.
5. Builder Design Patterns: Object Creation, Complex Object Creation, Keep Complex Object Creation separate from it’s representation.

For Factory: Simple Factory, Factory Method, Abstract Factory

Factory Method: Construction separated from implementation. Objects can be created without defining the exact class of object to be created.

Abstract Factory: One layer above Factory Method. Super Factory. Creates other Factories to create objects.

Builder Design Patterns: Helps to create complex objects. Uses construction methods/processes that can be used to create different representations of Objects. Step by step construction.

Commands from this URL worked. In my case, I only executed the above commands.

What are your thoughts?

It looks like, if I am to invest in Halal ETFs, the best available options are: SPUS, and HLAL – For Equity Part. SPRE and SPSK can be for the fixed income part. However, the performance of SPRE and SPSK is not great – you may also lose money.

You will buy all the above ETFs from USA-based exchanges (Canadian or other country brokerages may have the feature to buy). It brings some challenges such as currency conversion (charges), and probably some % are withheld if from a different country (Canadians may or may not have exemptions depending).

WSHR (Wealthsimple Shariah World Equity Index ETF ) can be an option from Canada (no currency conversion). However, the performance is not good at all.

It looks like: SPUS and HLAL are the way to go (at least to start with). Then probably look into SPRE and SPSK.
