You can open directory, for instance:

There is a README file that you can review first.

Structure of Readme

Here is some steps in each README file:

• 💡 Use Case: a short description about the specific problem that we want to solve.
• ❌ Bad Practice: a typical solution that works but not in a proper way.
• ✅ Good Practice: implementing the specified design pattern to solve the problem in a proper way.

Diagram: There is also a diagram to represent the oveview of the design pattern to understand better. This is an example:

How to Run

In the root directory, run:

$ npm install

To run the design pattern:

$ npm run -w PATTERN_NAME start

For instance PATTERN_NAME can be strategy-pattern

To run the bad practice:

$ npm run -w PATTERN_NAME start:bad
