Yup, AWS actually created a JS runtime called LLRT (Low Latency Runtime) based on QuickJS exactly for this purpose (reducing Lambda function cold start time). The Syntax podcast just released an episode with one of the developers behind LLRT.
I don't want to take any credit away from Fabrice Bellard and his work on QuickJS. All of the serverless QuickJS derivatives like Shopify's Javy and AWS's LLRT owe a debt of gratitude to Bellard. They're all very thin wrappers over QuickJS (which is by design obviously in order to reduce cold start times). Use whichever verb you prefer in place of 'created'.
