What does “powerful” mean, when discussing programming languages?

Question

In the context of programming language discussion/comparison, what does the term \"power\" mean?

Does it have a well defined meaning? Even a poorly defined meaning?

Answer 1

There are really only two meanings people are worried about:

"Powerful" in the sense of "takes less resources (time, money, programmers, LOC, etc.) to achieve the same/better result", and "powerful" in the sense of "is capable of doing a wide range of tasks".

Some languages are extrememly resource-effective for a small range of tasks. Others are not so resource-effective but can be applied to a wide range of tasks (e.g. C, which is often used in OS development, creation of compilers and runtime libraries, and work with microcontrollers).

Which of these two meanings someone has in mind when they use the term "powerful" depends on the context (and even then is not always clear). Indeed often it is a bit of both.
