A computer program is usually written in high level language described as a source code. The difference between an interpreter and compiler is the point at which a source code is actually executed. This means that when convert source code into machine code , we use either a compiler or an interpreter. So generally categorizing computer languages by "compiled" or "interpreted" doesn't make much sense. Now a days, interpreting Vs. compiling is a trade-off, with time spent compiling often being rewarded by better runtime performance , but an interpretative environment giving more opportunities for interaction .
