In the early days of microcomputers, like the Apple II, people wrote complete applications in Assembly Language, such as the first spreadsheet program VisiCalc. Many video games were written in Assembly Language to squeeze every bit of performance they could out of the hardware. Modern compilers, like the GNU C compiler, generate adequate code, and microcontrollers, like the RP2040, are much faster. As a result, most applications are written in a collection of programming languages, where each excels ...
