we programer write, read, eat and sleep in programming languages. it's our knife and hammer for building amazing things. and thinking goes together with building. this is the ability (to think) that separates us from ai. people thinks about stuff not just programmers but where we (programmers) differ from them - we think about weird stuffs. no, no, not just weird; really, really weird. like: what would happen if a programming language only had six instruction to work with? (spoilers: brainfuck). you already know these if you're a programmer. but do you know how your programming language works? why do you see hello, world by writing console.log("hello, world")? you know, console.log is a function, but what is a function? how does a function get associated with an object? how come you can write function x(): x() but not let x = x? you can read these how and why in books and stuff but it would be far more clearer if you write these behaviour (of object, function etc.) on your own.
why?
why bother writing a programming language?
if you know how programming languages works, your can work with them more efficiently. and further more, do want the most valuable tool in your toolbox to be a mystery to yourself? (hell, na!)
