API in JavaScript An API in JavaScript allows different software systems to communicate by sending and receiving data. APIs enable developers to interact with web services, retrieve data, or trigger actions using JavaScript. Common examples include REST APIs and browser APIs like Fetch or DOM. They simplify complex functions, making web applications more dynamic, interactive, and connected to external resources.
