��Representational State Transfer (REST) is a software
architecture style consisting of guidelines and best practices
for creating scalable web services. REST is a coordinated
set of constraints applied to the design of components in a
distributed hypermedia system that can lead to a more
performant and maintainable architecture.��

Node.js is a platform for building scalable server-side web applications using JavaScript. It uses non-blocking I/O and event-driven architecture to handle thousands of concurrent connections with high throughput and low latency. Some key features include using Google's V8 JavaScript engine, support for CommonJS modules, asynchronous and event-driven programming, and a large ecosystem of open-source modules. Node.js is particularly suited for real-time web applications that require bidirectional communication.

��ݧѧէڧާڧ� ��ڧԧ�� "��ѧ� Node.js"EPAM Systems

Node.js is a JavaScript runtime built on Chrome's V8 engine that uses asynchronous and event-driven programming to build fast and scalable network applications. It allows for non-blocking I/O operations through a callback pattern to prevent slow operations from blocking other operations. Node.js uses a single thread event loop model that handles concurrent operations without blocking. It can be used to build HTTP servers, watch files for changes, interface with databases like MongoDB, and create real-time web applications using web sockets. Node.js is well suited for real-time applications, APIs, and streaming but not for CPU intensive or data transformation tasks.
