Influence¶

Figure 1. Simula 67 in the influence graph: recorded ancestors on the left, languages that record it as an influence on the right. Every node links to its own record. Edges name indexed languages only, so an empty side means no indexed relative, not none at all. Source: languages.json.

Within the C family¶

Curly-brace syntax and an imperative core, descending from ALGOL through C. The tradition most later languages either extend or explicitly react against.

Language	First appeared	Typing	Memory	Execution
COBOL	1959	Static, weak	Static allocation	AOT compiled
ALGOL 60	1960	Static	Stack-based	AOT compiled
Pascal	1970	Static, strong	Manual	AOT compiled
C	1972	Static, weak	Manual	AOT compiled
Objective-C	1984	Static core with dynamic dispatch	Manual then ARC	AOT compiled
C++	1985	Static, partly weak	Manual with RAII	AOT compiled
Go	2009	Static, strong	Concurrent tracing GC	AOT compiled
Dart	2011	Static, strong, sound null safety	Generational tracing GC	JIT for development, AOT compiled for release
