As there are different strengths and weaknesses resulting from the design decisions chosen for the different languages, learn as many different types as you can and experience how they shape solutions to problems in different ways and how you reason about them. "I have never met anybody who has changed their reasoning first and their habits second. You change your habits first." The end goal is to solve problems in your domain, having a languages that maps perfectly to that domain (or makes it easy to create domain specific languages in) will certainly make it easier to read and write that code. But is it worth creating and maintaining that language for a small domain and train people in it? General purpose languages exists because of this. They might not map perfectly to the domain, but they have familiarity and cross breeding between users in different domains. Some languages are really small with little functionality included in the standard library, others are huge and contain a lot of seldom used functionality. For the small languages you might need to write common functionality yourself or find something someone else has written. For large languages you get that for free and most users will use what's provided. You get a standard way of solving problems, but the tools might not be best of breed or suit your specific use case. /Johan On Mon, Mar 17, 2014 at 11:38 AM, by <free7by@yahoo.com> wrote: > Yes, you are right, i have some prejudice for C++ before, but now, i think > i won't, cause if i have not deeply working for some languages, > technologies, i have no right to judge it, i need more and more practice : ) > Different fields got different technologies, the only key i think is that > which field you prefer, and what kind of technology you prefer. > > - by > > > On 2014/3/17 17:14, Johan Bucht wrote: > >> Working in higher level languages like Java, Ruby, Python and C++ does >> have >> some advantages to C and some disadvantages.
