MicroQuickJS: A Lightweight JavaScript Engine for Embedded Systems
By
Aissen
Crisp on the outside, thoughtful on the inside. A keeper.
Summary
MicroQuickJS (MQuickJS) is a lightweight JavaScript engine designed for embedded systems, requiring only 10 kB of RAM and about 100 kB of ROM. It compiles and runs JavaScript programs with speed comparable to QuickJS but implements a stricter subset of JavaScript close to ES5, forbidding error-prone or inefficient constructs. While sharing much code with QuickJS, it has different internals optimized for minimal memory consumption.
Key quotes
· 5 pulledMicroQuickJS (aka. MQuickJS) is a JavaScript engine targeted at embedded systems.
It compiles and runs JavaScript programs using as little as 10 kB of RAM.
The whole engine requires about 100 kB of ROM (ARM Thumb-2 code) including the C library.
MQuickJS only supports a subset of JavaScript close to ES5.
Although MQuickJS shares much code with QuickJS, it internals are different in order to consume less memory.
