I rewatched Stranger Things season 4, which takes place in 1986, and there’s a scene where code flashes on the screen while they’re “hacking”. It shows:
- Turbo C++ - not invented until 1990
- HTML - 1993
- HTTPS - 1994 (it’s called htsps on the screen)
- PHP - 1995
- CSS - 1996
- Iframe - 1997
- C# - 2000
- .NET Framework - 2002
- CoffeeScript - 2009
- Flexbox - 2009
