What does the code that makes up programming languages look like?

1.16K views

Take a language like Java. How was it originally created? I can’t wrap my head around how someone invented a computer language to run without having some “prior” language that it allows the first lines to function. Is it just Java all the way down, like someone wrote a single line of Java and then every other line was built on that?

What about the first computer language? What was the basis that that functioned on?

Thanks for any help, I hope that was phrased in a mildly intelligible way.

Edit; I’m trying to think of it like human language: at some point there was a first “word” spoken by someone and understood by another and from there the structure started to be born. What were the first “words” on a computer that led to where we are now?

It is hard to wrap the head around it because there are layers and layers and layers of abstraction. When taken one at a time, each one of them is much easier to understand, at least on the level of ELI5.

I highly recommend this youtube series: https://youtube.com/playlist?list=PL8dPuuaLjXtNlUrzyH5r6jN9ulIgZBpdo They explain everything more or less like eli5, starting from the bottom and going up that ladder of abstractions. Very entertaining, too.
