Some of the advantages of LuaJIT over Lua because of the presence of a rapid baseline interpreter. The reasons for the inclusion of baseline interpreter in LuaJIT and its advantage over Lua are mainly for the following reasons:

  • The interpreter used in LuaJIT uses a customary bytecode format that allows decoding an instruction at a much faster rate than Lua. For instance, Lua 5.1 uses the format that requires decoded with greater expertise, however, using LuaJIT aids decoding the bit at a faster rate.
  • LuaJIT has the interpreter written in assembly, which aids in outsmarting the compiler in comparison to Lua, therefore, making processing easy.
  • LuaJIT uses a direct dispatch in order to implement codes from the C programming language. Instead of using the conventional “loop” and “big switch”, LuaJIT uses a table of code labels, which each give a particular instruction to the decoder. If this particular needs to be performed in C programming language then a special instruction of GNU or Clang must be utilized and cannot be performed using ANSI C.
