Yes. Examples like the one linked make it appear that awk is write-only language, which it really isn't.

'awk' is really a very beautiful little language. It's concise enough to solve many tasks in a single line, making it easy to use interactively while still being able to grow to moderately-sized scripts. It's not supposed to replace a full-blown scripting language like Python, but for processing files line-by-line it's superb.
