The builder pattern. When developing your app, sometimes you may encounter difficulties in constructing complex objects.
Before we will go over the builder design pattern, let’s briefly go over design patterns in general.
A design pattern is a general and reusable solution for common problems you may encounter when designing your software. Each design pattern solves a different problem and can be customized to your use case with much ease.
One of the main reasons we need design patterns is to make our software very changeable, so it will be maintainable and will support future changes.
All software programs have to change and modify or they will cease to exist. The amount of time we spend on maintaining a software program is bigger than the amount of time it takes us to develop the program.
