Node.js
It is an open-source, cross-platform JavaScript runtime environment that is used to build data-centric, real-time solutions.
Talking about its application in IoT, it can be used to handle a large number of requests generated by devices such as sensors, beacons, transmitters and motors. In fact, Node.js makes the request-response flow smoother and faster.
Moreover, sockets and MQ Telemetry Transport (MQTT) protocol are well suited in Node.js which are normally used for continuous data transmission in IoT applications.
Node.js comes with the NPM (Node Package Manager) equipped with more than 80 packages for IoT-application cable boards such as Arduino controller, BeagleBone Black, Raspberry Pi and Intel IoT Edison. This means that you can rapidly develop robust IoT applications with Node.js development services.
Memory Management
In languages like C, developers need to manually allocate and deallocate the memory using methods like the malloc(), calloc(), realloc(), and free(). In languages such as JavaScript, there is no need to explicitly allocate or release memory.
Also known as Garbage Collection, JavaScript values are allocated when things are created (objects, strings, etc.) and freed automatically when they are no longer used (i.e. automatic allocation and deallocation).
The garbage collector feature allows IoT developers to focus on aspects of development rather than wasting time on memory management. In a way, the automatic freeing of the unused memory results in a stable IoT solution as the garbage collector eliminates memory leaks.
Event-Driven Programming
In event-driven applications, every device reacts to various events by responding with an appropriate activity. JavaScript is great with event-driven applications.
Event loops in JavaScript allow you to run various tasks without waiting for other tasks to be completed. This helps in responding to events in real-time, handling multiple tasks simultaneously and allowing multiple devices to respond to the same event.
JavaScript’s support for event-driven programming contributes to a great extent in optimizing battery power. Read More
