How Can I Dynamically Generate Complex JSON Objects in Go?

Dynamically Generating Complex JSON Objects in Go

Golang requires maps to declare types explicitly, limiting the ability to create JSON objects with diverse data types. However, the solution lies in leveraging interface{} to store any data type.

According to the encoding/json package documentation:

If the interface value is nil, ... Unmarshal stores one of these in the interface value:

• bool for JSON booleans
• float64 for JSON numbers
• etc.

To create a dynamic JSON object:

m := map[string]interface{}{"a":"apple", "b":2}

This code creates a map that can be transformed into a JSON object with both a string and an integer value, as desired. By using interface{}, the code is flexible and accommodates data types determined at runtime.
