Objective-C is a statically typed, object-oriented language primarily used for iOS and macOS development, offering strong performance and memory management. In contrast, JavaScript is a dynamically typed, highly flexible language used for web development, supporting both front-end and back-end, but may suffer from performance and compatibility issues.
