Description: Edge functions in JavaScript are snippets of code that run at the edge of the network, meaning on geographically distributed servers that are closer to end users. This allows for data processing and application logic execution without the need to send all information to a central server, reducing latency and improving efficiency. These functions are particularly useful in applications that require quick responses and real-time processing, such as in interactive web applications, IoT, and streaming services. By executing at the edge, these functions can access local data, perform transformations, and send only the necessary information back to the main server, thus optimizing bandwidth usage and enhancing user experience. Additionally, edge functions can integrate with other technologies, such as APIs and databases, to provide more comprehensive and scalable solutions. In summary, edge functions in JavaScript represent an evolution in how applications are developed and deployed, enabling more agile and efficient processing in the era of edge computing.
