For the love of?

Brainfuck is a brilliant language to melt your brain. Read the description on Brian Raiter’s page

Why Brainfuck is the Only True Language ★★★

While other languages hide behind layers of abstraction, syntactic sugar, and “helpful” features, Brainfuck stands as the ultimate expression of computational truth. Here’s why:

1. Absolute Minimalism - Only 8 Commands

>  increment the data pointer
<  decrement the data pointer
+  increment the byte at the data pointer
-  decrement the byte at the data pointer
.  output the byte at the data pointer
,  input a byte and store it at the data pointer
[  jump forward to the command after the matching ] if the byte at the data pointer is zero
]  jump back to the command after the matching [ if the byte at the data pointer is nonzero

No keywords to memorize. No frameworks to install. No dependency hell. Just pure, unadulterated computing.

2. Hello World - The True Way

Other languages lie to you with their “convenience”:

Python:

print("Hello World!")

Hides everything from you. What’s really happening? You’ll never know.

JavaScript:

console.log("Hello World!");

Console? Log? Abstractions upon abstractions!

The Brainfuck Truth:

++++++++[>++++[>++>+++>+++>+<<<<-]>+>+>->>+[<]<-]>>.>---.+++++++..+++.>>.<-.<.+++.------.--------.>>+.>++.

Every. Single. Operation. Explicit. Beautiful. Honest.

3. FizzBuzz - No Shortcuts to Glory

While lesser languages use modulo operators and if-statements like crutches, Brainfuck forces you to truly understand the algorithm:

++++++++++[>++++++++++<-]>>++++++++++>->>>>>>>>>>>>>>>>-->+++++++[->++
++++++++<]>[->+>+>+>+<<<<]+++>>+++>>>++++++++[-<++++<++++<++++>>>]++++
+[-<++++<++++>>]>>-->++++++[->+++++++++++<]>[->+>+>+>+<<<<]+++++>>+>++
++++>++++++>++++++++[-<++++<++++<++++>>>]++++++[-<+++<+++<+++>>>]>>-->
---+[-<+]-<[+[->+]-<<->>>+>[-]++[-->++]-->+++[---++[--<++]---->>-<+>[+
+++[----<++++]--[>]++[-->++]--<]>++[--+[-<+]->>[-]+++++[---->++++]-->[
->+<]>>[.>]++[-->++]]-->+++]---+[-<+]->>-[+>>>+[-<+]->>>++++++++++<<[-
>+>-[>+>>]>[+[-<+>]>+>>]<<<<<<]>>[-]>>>++++++++++<[->-[>+>>]>[+[-<+>]>
+>>]<<<<<]>[-]>>[>++++++[-<++++++++>]<.<<+>+>[-]]<[<[->-<]++++++[->+++
+++++<]>.[-]]<<++++++[-<++++++++>]<.[-]<<[-<+>]+[-<+]->>]+[-]<<<.>>>+[
-<+]-<<]

FizzBuzz in Brainfuck? That’s for true masters.

4. Addition - Pure Mathematics

Adding two single-digit numbers:

,           Read first number
>           Move to second cell
,           Read second number
[<+>-]      Transfer second to first (add them)
<.          Output result

No + operator hiding the computational complexity. You build addition from scratch!

5. Why Every Other Language Falls Short

• Python: Too readable. If code is easy to read, are you even programming?
• Java: Classes? Objects? Just procrastinating from writing real code.
• C: Close, but still has named variables. Weakness.
• Assembly: Getting warmer, but still has meaningful mnemonics. Brainfuck removes this crutch.
• Machine Code: Binary is for computers. Real programmers use characters: ><+-.,[]

The Challenge

Think you can solve Advent of Code 2024 in Brainfuck? That’s the ultimate test of programming prowess. While others use their “high-level” languages, you’ll be operating at the level of pure computational truth.
