Using JerryScript on ESP32

JerryScript is the lightweight JavaScript engine intended to run on a very constrained devices such as microcontrollers:

• Only few kilobytes of RAM available to the engine (<64 KB RAM)
• Constrained ROM space for the code of the engine (<200 KB ROM)

The engine supports on-device compilation, execution and provides access to peripherals from JavaScript.

Using JerryScript

JerryScript needs a heap, if you have external PSRAM, add the following configuration to your sdkconfig.defaults

CONFIG_JERRYSCRIPT_MALLOC_STRATEGY_SPIRAM=y
CONFIG_JERRYSCRIPT_HEAP_SIZE=128

Have a look at the example code: hello_world
