Dates are first public release or publication, not the start of internal development. Colour on the typing and memory tags encodes kind, never rank.
Influence¶
Within the Dynamic scripting¶
Late binding and rapid iteration, usually paired with a large package ecosystem and an interpreter or JIT.
| Language | First appeared | Typing | Memory | Execution |
|---|---|---|---|---|
| BASIC | 1964 | Dynamic, weak | Interpreter-managed | Interpreted |
| Smalltalk-80 | 1980 | Dynamic, strong | Tracing GC | Bytecode VM |
| Perl | 1987 | Dynamic, weak | Reference counting | Interpreted |
| Self | 1987 | Dynamic, strong | Generational tracing GC | JIT |
| Python | 1991 | Dynamic, strong | Refcount with cycle collector | Interpreted |
| JavaScript | 1995 | Dynamic, weak | Tracing GC | JIT |
| PHP | 1995 | Dynamic, weak | Refcount with cycle collector | Bytecode VM |
| Ruby | 1995 | Dynamic, strong | Tracing GC | Bytecode VM |
| TypeScript | 2012 | Static, erased at runtime | Tracing GC (host) | Transpiled to JavaScript |
