What are the main differences between the fmt package and other formatting packages?

The fmt package in Go is primarily used for formatted I/O. It provides functions for formatting strings, printing to the console, and more. Other packages may offer similar functionalities but can differ in performance, features, or ease of use.

Can you give examples of other formatting packages?

Sure! Some examples include the 'text/template' and 'html/template' packages in Go, which are used for generating text and HTML output, respectively. They offer more specialized formatting options compared to fmt.

Which package is better for performance?

It depends on the use case. The fmt package is generally efficient for basic formatting tasks, but for more complex templates, 'text/template' might be optimized for that specific purpose.

Are there any limitations of the fmt package?

Yes, the fmt package is not designed for complex data structures or custom formatting. For those cases, using other packages like 'text/template' might be more suitable.
