This book introduces a new approach to embedded development, grounded in modern, industry-standard JavaScript. Using the same language that powers web browsers and Node.js, the Moddable SDK empowers IoT developers to apply many of the same tools and techniques used to build sophisticated websites and mobile apps.

In this special edition, you will find interviews with members of the Espressif community, special projects we at Espressif do in our spare time, and real-life examples of how the Espressif community is helping make the connected world a better place.

The ESP32 chip will be the heart of most of the projects we are going to build in the near future, because it offers everything we need in one low cost solution! This chip is Dual Core! It offers two 32Bit Processing Units. One is responsible for the WiFi connectivity and the other one is available for executing our code! The typical frequency of the CPU cores is 160MHz which is double than the operating frequency of the ESP8266.
