Question

Which is more memory efficient interpreter or compiler?

Answer 1

compiler is more memory efficient cause it's do more converting

Answer 2

Both compiler and interpreter take a different approach for  conversion of source code into machine code and bytecode.

Compiler executes conditional control statements (like if-else and switch-case) and logical constructs faster than an interpreter.

The interpreter executes conditional control statements at a much slower speed.

Compiled programs take more memory because the entire object code has to reside in memory.
