“Every language was created for a specific purpose”

Question

I was reading the post Why Language is Important (Why I prefer C#) from \'Dot Net Thoughts\' and the first paragraph of the article ends with this statement:

Answer 1

Fortran - to run numerical calculations as fast as possible.

Answer 2

Brainfuck exists to show you can write a compiler for a Turing complete language in under 200 bytes :)

Answer 3

INTERCAL: To raise the perceived intelligence of developers by making their code so confusing no one else understands it. =:)

Answer 4

J

J is particularly strong in the mathematical, statistical, and logical analysis of data. It is a powerful tool in building new and better solutions to old problems and even better at finding solutions where the problem is not already well understood.
