Direct answers to what things actually mean — no filler.
Flutter Impeller
Impeller is Flutter's newer rendering engine, built to replace Skia. It precompiles shaders ahead of time instead of compiling them on first use, which eliminates the shader compilation jank that caused visible frame hitches in Skia-based Flutter apps, especially on iOS.
ReadEdge SSR
Edge SSR is server-side rendering executed on edge compute infrastructure (like Cloudflare Workers or Vercel Edge) distributed across many global locations, rather than a single origin server. This cuts network latency by running the render close to the requesting user, at the cost of a more constrained runtime (no full Node.js APIs, stricter memory/CPU limits).
ReadWebAssembly (Wasm)
WebAssembly (Wasm) is a binary instruction format that runs in web browsers at near-native speed, alongside JavaScript. It's typically compiled from languages like Rust, C++, or Go, and used for computationally heavy tasks (image/video processing, cryptography, physics simulation) where JavaScript's performance isn't sufficient.
