JerryScript is a lightweight JavaScript engine for resource-constrained devices such as microcontrollers. It can run on devices with less than 64 KB of RAM and less than 200 KB of flash memory.

Key characteristics of JerryScript:

• Full ECMAScript 5.1 standard compliance
• 160K binary size when compiled for ARM Thumb-2
• Heavily optimized for low memory consumption
• Written in C99 for maximum portability
• Snapshot support for precompiling JavaScript source code to byte code
• Mature C API, easy to embed in applications

Additional information can be found on our project page and Wiki.

Memory usage and Binary footprint are measured at here with real target daily.

Write local state using React Hooks and lift it up to React Context only when needed with minimum effort.

import React, { useState } from "react";
import constate from "constate";
// 1️⃣ Create a custom hook as usual
function useCounter() {
  const [count, setCount] = useState(0);
  const increment = () => setCount(prevCount => prevCount + 1);
  return { count, increment };
}

// 2️⃣ Wrap your hook with the constate factory
const [CounterProvider, useCounterContext] = constate(useCounter);

function Button() {
  // 3️⃣ Use context instead of custom hook
  const { increment } = useCounterContext();
  return <button onClick={increment}>+</button

Fast and lazy collection operations

Working with methods like .map(), .filter() and .reduce() is nice however they create new arrays and everything is eagerly done before going to the next step.

This is where lazy collections come in, under the hood we use iterators and async iterators so that your data flows like a stream to have the optimal speed.

All functions should work with both iterator and asyncIterator, if one of the functions uses an asyncIterator (for example when you introduce delay(100)), don't forget to await the result!

let program = pipe(
  map((x) => x * 2),
  filter((x) => x % 4 === 0),
  filter((x) => x % 100 === 0),
  filter((x) => x % 400 === 0),
  toArray
