the Option Pattern to Write

 Using the Option Pattern to Write Better Go Code

Go structs with numerous fields are common, which can make initialization difficult, particularly if some of the fields are optional.

When there are a lot of different setup combinations, it gets increasingly harder.

Using the option pattern—which is extensively utilized in numerous Go libraries, including net/http, sqlx, and gorm—is one approach to solving this issue.

Functional options offer a flexible interface that can be expanded without disrupting the current API, as opposed to function overloading, which can complicate the codebase.

The option pattern is a popular way to make struct initialization in Go simpler. Rather than specifying numerous constructors with disparate parameters, we can specify a
