to develop the language of choice, we must first understand its characteristics, and then according to the actual needs to consider a variety of factors to analyze the selection of the appropriate language
For example:
Structure-oriented, object-oriented , parallel functional, what is the programming model that best fits the requirements? What is the most appropriate language to excel at this model?
what is needed most in demand? Operational efficiency, development efficiency? Flexibility, security, complexity? or other, the most important thing is that?
What kind of efficiency do we need to be? The ultimate in efficiency? Meet the efficiency of the benchmark?
How much flexibility do we need (at design time and at runtime)?
What is the point of our fault tolerance? (Can crash test iterations (strong check strong test)? Generally does not crash (script)? )
other considerations, etc...
of course, the more lazy way, is to go with the crowd, generally will not be wrong, the development of operating systems with C, the development of the game engine with C + +, the development of the web with java,php, etc., especially recommended parallel cloud computing with Erlang.
