Hey everyone, I built Sigment to push JS performance to the limit and see how close a framework can get to the raw speed of the browser. After months of optimization, I finally ran the official JS Framework Benchmark, and the results blew me away. 🚀 The Result: 1.06 Weighted Geometric Mean As you can see in the full table above, Sigment achieved a weighted geometric mean of 1.06. For context, that puts it neck-and-neck with Vanilla JS (1.03) and significantly faster than most popular frameworks. But the real shocker was the "Select Row" test: Vanilla JS: 2.6ms Sigment: 2.2ms 🚀 How is Sigment faster than Vanilla JS here? It sounds like magic, but it’s down to architecture. While a typical 'unoptimized' Vanilla implementation might use generic event delegation or manual DOM lookups, Sigment uses direct-access pointers to DOM nodes via its internal gve function. By bypassing standard reconciliation layers, it can execute specific updates even more efficiently than traditional imperative code.…
