I posted here a while back after being stuck on chapter 1.

I have completed the first 3 chapters of the book (~500 pages), including most of the exercises and lectures up till that point.

But chapter 4 with its metacircular evaluator just straight up demoralised me.
I COULDN'T UNDERSTAND SHIT. It became way too abstract and all the exercises are now about engineering your own evaluator.

So tell me, should I continue and finish the whole book? Is it worth slugging through chapter 4 and 5? I don't see how the book can be beneficial for me now, as chapter 4 and 5 are way too esoteric. Also, my university stops at the metacircular evaluator so I can kinda stop reading the book if the rest of the content doesn't help me.

I think it should be fine. However do take note that the programming language itself is Source, a derivative of Javascript. Use this website to write your code. https://sourceacademy.nus.edu.sg/playground

Also, I chose to do the original MIT Scheme as there are more resources available for it (solutions to exercises, lectures, etc). Thus, I would recommend that you do the original SICP text as well, as attemping the exercises is absolutely essential to understanding the text. Good luck.

>> No.11706742

>>11706725
Hm interesting. Is this a bad way to practice JavaScript indirectly then since you're using a weird derivative?

>>11706742
The text itself teaches you about essential programming techniques that can be applied to any language, so the language itself is not that important, since you can learn the barebones of a language pretty quickly.
I am not quite sure of how similar Source is to Javascript, but it should be fine I guess.

Yeah ik the language isn't the point but context switching is annoying. If it doesn't look like C/Python/JS my brain just doesn't like it

>Why is SICP so hard?
It's poorly written and not well structured. I vastly superior version teaching the same things can easily be written and most likely already exists. SICP is obsolete trash.

Not familiar with C, but assuming int goes from -2^31 to 2^31-1, last iteration of loop will have a = 2^31-1, then post-increment to -2^31. Pre-increment on line 7 bumps it to -2^31+1, so "Classic Nigger" is printed

This, isn't it undefined behavior on most (all?) modern computers and compilers anyways because of the signed int overflow?

nope retard, it's classic nigger always.
int is always 32bit even on 64 bit system.

It’s fine. It’s not too hard. Just focus on your basics. Sketching things out is your best friend. Once you understand abstraction to its fullest extent, you’ll be able to tackle the eval part of the loop. It just takes time.
