In this blog, we will learn more about
👉 Constructor Pattern

Constructor Pattern

In simple terms, a Constructor pattern is a method which creates and initialises objects of the same type. It falls under Creational patterns
As the name suggests, it is a class-based approach but let's understand it in both ways (functional & class).

How does Constructor Pattern work?
To understand it better, Let us take an example

Steve had a boutique, where he manufactures high-quality shirts and also customers like his collections and purchase them.
He imports High-quality fabrics from different countries which is a primary reason for his successful business. In his manufacturing factory, everything is automated with different machinery. For all his machines, there is a common
process followed to get similar shirts.

Now, let’s see how the constructor pattern is applied here.

Check out the working code here for class-based

Note: please use the browser console to check the output

This is how the process is set for manufacturing shirts.
To grow the business, Steve purchases a few more machines but still, the process would be the same.
In simple terms, a Constructor Pattern is a blueprint that can be used for creating similar objects.

Now, we know the working of the constructor pattern. let’s know when to use this.

When to use the Constructor pattern?

As the definition clearly depicts constructor pattern is used to create objects of the same type.
All the plugins, packages, libraries, etc which we use in our projects are nothing but the best examples of constructor patterns.
