Wow, you actually stated something that was wrong enough to force me to comment. The beauty of these tools are that they are small, fast, ubiquitous, AND easy to replace with other tools if they fit your problem better. Unix was built exactly for swapping in these small one-off programs and to deny that is to deny the beauty of it's design and to basically ignore the fact that the system is built to string arbitrary programs together to solve complex problems in simple ways. One advantage of her Javascript replace is that she can drop it on any machine with a Javascript runtime and it will work, unlike sed. And the real truth is, she wrote something that solves a problem she has, which is the measure of her success, not someones arbitrary comments.
