Edge functions: good for performance and cost, hard to debug and integrate, states new survey

Edge functions are a new modern approach to web application development that integrates with third-party APIs to reduce frustration. The traditional way of web application deployment involves hosting a server, using a load balancer, and executing a content delivery network. Cloud providers like AWS, Google, and Azure have made edge functions a natural fit with their cloud infrastructure. Although, there are challenges with debugging live functions and distributed database synchronization. Typescript is the most popular programming language for edge function development.
