In most programming languages, there’s a trade off between efficiency, and ease of use. It’s a spectrum of the two, for example, C would be on the efficiency side, and Javascript would be on the ease of use side. But both are usable for making large programs, there’s only a few languages you can think of so effecient that it is barely usable for the average programmer. You may have in mind x86 assembly, Fortran, or another archaic language.
