It acts as an intermediary between the operating system and the application, ensuring consistent behavior across different platforms and hardware.

/ˈrʌn.taɪm/

noun — "when your code finally leaves the editor and starts making decisions on its own."

Runtime refers to the period during which a program is executing, from start to finish, and the environment in which it runs. It encompasses the system resources, libraries, and virtual machines that support the program, as well as the dynamic behavior of the code, such as memory allocation, exception handling, and I/O operations. Understanding runtime behavior is crucial for performance optimization, debugging, and ensuring reliability.
