Get ready to unleash the raw truth about WebAssembly! In this episode of WebAssembly Unleashed, hosts Joel Moses, Oscar Spencer, and Matt Yacobucci are joined by guest Pat Hickey for a no-holds-barred deep dive into the latest proposals and advancements shaking up the WebAssembly space. From phase five proposals like tail calls and extended constant expressions to the thorny complexities of garbage collection, multiple memories, and relaxed SIMD—the team doesn’t mince words as they dissect what works, what doesn’t, and what might blow up next. They even take aim at JavaScript integrations, content security policies, and the messy evolution of threading in Wasm. If you're looking for unfiltered, expert takes on what's promising, what's polarizing, and what's downright contentious in the world of WebAssembly, this is an episode you cannot miss. Buckle up!
