Builder Pattern
The Builder Pattern is a creational design pattern used in software development to construct complex objects step by step. It separates the construction of an object from its representation, allowing the same construction process to create different representations. This pattern is particularly useful when an object requires many parameters or has optional components, making constructors unwieldy.
Developers should use the Builder Pattern when dealing with objects that have many optional parameters or complex initialization logic, as it improves code readability and reduces the risk of errors from telescoping constructors. It is commonly applied in scenarios like building configuration objects, creating immutable objects, or handling objects with numerous fields, such as in data models or API request builders. This pattern also enhances maintainability by making it easy to add new parameters without breaking existing code.
