I believe most people still know too much about this knowledge, so share this article for your reference. I hope you can get something after reading this article. Let's take a look at it.

Effect.

It gives you finer control over the construction process.

The Builder pattern is different from the creative model that generates the product all at once, it constructs the product step by step under the control of the director. The guide retrieves the product from the generator only when it is completed. Therefore, the Builder interface can better reflect the construction process of the product than other creative modes. This gives you finer control over the build process and thus finer control over the internal structure of the resulting product.

This is one of the important differences between Builder mode and workshop mode. The factory pattern (simple factory or abstract factory) is to call the interface to produce the product directly, and the user cannot intervene in the intermediate process. The Builder mode can control the product generation process step by step when creating the product. This process is often inexpressible by parameters.

Also, abstract factory patterns typically change from one representational factory class to another; Builder often replaces Director in addition to the representational Builder. What's more, there are a considerable proportion of scenarios that control Director to generate another (rather than another) product by passing different data to Builder. In this case, you can also consider not designing the inheritance relationship of Builder for the time being. It is not too late to ReFactor when the need to replace Builder arises.
