Scripting Languages, cont'd
Interpreted:
- Rapid development.
- Extend applications on the fly.
- Less efficient than system programming languages.
High level: each statement does more work.
- Scripting: 100-1000 instructions/statement.
- System programming: 5-10 instructions/statement.
Rapid development:
- 5-10x faster than system programming languages (for gluing tasks).
Still safe: detect errors at runtime.
Use computers less efficiently, use people more efficiently.
