Runtime model
The Pharo runtime, written in C, manages the execution of Pharo programs. Runtime-based languages rely on a host process to interpret or compile code at runtime rather than compiling entirely ahead-of-time to native machine code. This means running Pharo programs requires the runtime to be present on the target system.
The choice of C for the runtime gives Pharo access to native performance, established platform abstractions, and existing ecosystem libraries.
