ELIMINATING JAVASCRIPT COLD STARTS ON AWS LAMBDA

Summary from the TLDR Web Dev newsletter

Porffor is a new JavaScript engine that compiles JS code ahead-of-time to WebAssembly and native binaries, creating much smaller and faster executables compared to Node.js and other runtimes. In AWS Lambda cold start benchmarks, Porffor performed ~12x faster than Node.js and ~4x faster than Amazon's LLRT while being over 2x cheaper to run than Node.js. However, Porffor is still in pre-alpha development with limited JavaScript support and no current Node.js API compatibility, making it unsuitable for production use yet.
