Can somebody help me understand this code?

Question

I want to understand it. I know basic js, but I think understanding this code will help me understand js better.

None of it was explained in w3schools.

Answer 1

@Daniel Cooper , its a very nice code of syntax highlighting, seeing it I now realize that I used it a lot when practicing on w3schools, nice.

btw even if we write a detailed description of it it ll be use useless,
my advice is go though the
main w3CodeColor() function and ask which part you are stuck.

in the heart of it is the extract constructor function, whose job is to extract strings as an object and apply styles then in the end merge them together.

I would suggest to study first only the htmlMode function, then you can easily figure out cssMode and jsMode.

heres a stripped version of it with 100 lines

Answer 4

Jay Matthews Lol. I found this on w3schools. If you can find a better way to do this, than please tell me xD

Answer 5

I thought about it Calviղ

But since this code was written, I just assumed it was the simplest way. I'm new to coding so I assumed. Remind me not to do that xD

I mean, why post such a complex code when it could easily be simplified? Lol

Lol. Regardless, I'll try using regexp.

Answer 6

I didn't really expect anyone to do it. This was just posted in case someone had some time xD

And no I'm not alright
My brain has been damaged by the Oklahoma heat :(

Answer 7

Use regex could simplify it.
