An SDK, or Software Development Kit, is a bundle of tools, libraries, documentation, and code samples to assist developers in creating applications for certain platforms or services.
SDKs can be specific to operating systems, programming languages, services or APIs, and hardware devices.
Key components of an SDK include libraries and frameworks, documentation, code samples and examples, IDE plugins, debugging and testing tools, and command-line tools.
SDKs offer advantages such as faster development, standardization, improved security, access to advanced features, and better performance.
