JavaScript APIs

JavaScript APIs can be categorized into high-level and low-level APIs based on their abstraction and the level of detail they expose to developers. High-level APIs provide more abstraction, making it easier for developers to work with certain functionalities without delving into intricate details. On the other hand, low-level APIs offer more control and detail, allowing developers to fine-tune their implementations.
