The counter application has evolved to effectively process input files, displaying results for words, lines, and bytes accurately. However, a subtle output formatting issue arises, particularly when handling varying file types, including empty files. In contrast to the `wc` command, which aligns its output neatly in a tabular format, the current implementation shows staggered results. To enhance readability, the Go `Tab Writer Package` is introduced, which allows for improved column alignment using the `ElasticTabStop` algorithm. By modifying the code to incorporate this package, including adjusting parameters for minimum width and tab widths, the output can achieve right-aligned numerical columns while maintaining left-alignment for filenames. Furthermore, lessons emphasize the importance of flushing the writer to avoid data loss during execution and provide an assignment that challenges learners to implement a header for better context in output results. As the module concludes, learners are prepared to explore more advanced features of Go, including concurrency and end-to-end testing.
