by default no, espruino interpreter runs the source directly as per https://www.espruino.com/Performance , that's why it is important to minify and pretokenize before upload. there is however flag
pretokeniseset by E.setFlags which behaves like this when loading file from storage (?) see https://www.espruino.com/Reference#l_E_getFlags , also there is"ram"attribute in function body that will copy it to ram (for speed critical code).
