What is ActionScript written in?
ActionScript is an object-oriented programming language, first released in 1998.
Implementation
| Layer | Written in | Notes |
|---|---|---|
| Runtime | C++ | ActionScript 3 ran on the Tamarin VM, written in C++. |
Runtime model
The ActionScript runtime, written in C++, manages the execution of ActionScript 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 ActionScript programs requires the runtime to be present on the target system.
The choice of C++ for the runtime gives ActionScript access to native performance, established platform abstractions, and existing ecosystem libraries.
