Wtf does this do

The README for this project is essentially empty, so there's limited information to work with. Based on the repo name and description alone, here's what we can infer: This is a testing project designed to see how web browsers and JavaScript frameworks handle extremely large tables, think thousands or millions of rows of data. Instead of just assuming a framework will work fine with huge datasets, the creator is actually testing it to measure performance and understand where things might slow down or break. The practical use case is straightforward: if you're building a web application that needs to display a lot of tabular data (like financial records, analytics dashboards, inventory systems, or log viewers), you want to know ahead of time whether your chosen JavaScript framework can handle it smoothly. Without testing, you might ship something that freezes or crashes when users load real-world data. This repo is a way to benchmark that behavior systematically. The README doesn't go into detail about how the tests work or what frameworks are being compared, so it's hard to say exactly how you'd use this code. It appears to be a small, experimental project, the kind of thing a developer might create to answer a specific technical question they had. If you're curious about JavaScript performance at scale, this would be the type of repository to check out, but you'd likely need to read the actual code or run it yourself to understand the results.
