Sure, JavaScript is a universal programming language applied for front-end and back-end development, and it's often employed by developers for IoT projects. There are several compelling reasons. First, it has a low entry-level and accessible coder, allowing developers to handle development and scale the project efficiently. Secondly, JavaScript allows you to build dynamic interfaces for many different devices. Thanks to the structure of the JSON format, it's easy to work with data from the device interface. Event-driven architecture is another benefit of JavaScript. This means that we can run many tasks simultaneously without waiting for other tasks to be completed. The language is easy to implement and works best in many different environments.
