Node.js, known for its asynchronous and event-driven architecture, is a popular choice for building scalable server-side applications. One of its primary uses is to create and manage APIs (Application Programming Interfaces). APIs allow different software systems to communicate and share data with each other. In Node.js, API functions can be categorized based on their nature, usage, and the type of data they handle. This article explores various types of API functions in Node.js, providing insights into their functionalities and use cases.
