What do you do with this data next?

After receiving data, the following steps are usually performed depending on the context of the task:

1. Validation and cleaning of data — checking correctness, removing unnecessary parts, converting formats.
2. Processing and analysis — calculations, filtering, aggregation, applying business logic.
3. Saving or transmitting — writing to a database, sending to another service or component.
4. Display or usage — output to the user, use in further calculations or processes.

For example, if the data are results of an API request, after receiving them, you can parse, check for errors, convert to the required structure, and use for decision-making or display in the interface.

In Go, this might look like:

// Received data in rawData
var data SomeStruct
err := json.Unmarshal(rawData, &data)
if err != nil {
    // error handling
}
// Then use data as intended

Thus, further actions depend on the goals and the context of working with the data.
