The njs interpreter implements ECMAScript standards and allows extending nginx's capabilities for handling requests through scripts in the configuration. Scripts can be used in the configuration file to define advanced request handling logic, generate configurations, dynamically create responses, modify requests\/responses, or quickly create stubs to solve problems in web applications. In the new version, methods Promise.all(), Promise.allSettled(), Promise.any(), and Promise.race() have been added to the implementation of Promise. Support for the AggregateError object has been implemented.<br \/>\n<br \/>Source: <a content=\"nofollow\" rel=\"nofollow\"
