Interpreted language: What is its benefit for being written in that way ?

Whenever I search in google why a specific language is interpreted language, I get differences between compiled languages and interpreted languages but nowhere the benefit for being interpreted rather compiled. Anyone please shed some light.

Interpreters are easier to write than compilers. For this reason esoteric and toy languages are often implemented by interpretation.

But the dichotomy between interpreted and compiled languages is a false one:

  • a sufficiently popular language which initially has only an interpreter may well later gain a compiler for performance reasons (see: Python vs Cython, pypy, etc; PHP vs HHVM).
  • other popular platforms use hybrid approaches whereby source code is compiled to a bytecode for a virtual machine, and then the bytecode is interpreted or part interpreted and part JIT-compiled (see: Java, .Net).

+1 for pointing out the false dichtomy. It might be worth adding why interpreters are easier to write; e.g. no need to do register allocation.

There're some inaccuracies in the examples given. E.g., "Python vs CPython" is incorrect b/c Python is basically a language specification. CPython is not a "compiler" for Python; it's the reference runtime implementation - but it's still an interpreter, not a compiler. Another example includes IronPython, which is a .Net-based runtime.

@ghost-in-the-zsh, not CPython, Cython.

@PeterTaylor: I guess I must've misread that as CPython for some reason. My bad. Also, I didn't get a notification... I just happened to check and see your comment.
