What's Your Coding Quirk?

#discuss #watercooler

If the debuggers captured a candid shot of you coding, what quirky behavior, habit, or unusual thing would they discover?

In JS, to add +1 value I don't usually use the ++ operand, instead I use += 1...

let conter = 0;

// Drake meme: rejecting
counter ++;

// Drake meme: approving
counter += 1;

It just feels more semantic to me, haha.

I'd be fine with both of those but I also relish in exploiting post-increment. *dst++ = *src++ yesss

What it does??

It's a string-copying idom in C. Full context:

/* copy string into buffer */
void strcpy(char *dst, char *src) {
        while (*src)
                *dst++ = *src++;
}
Enter fullscreen mode Exit fullscreen mode

It's equivalent to:

void strcpy(char *dst, char *src) {
        while (*src) {       /* while src isn't pointing to nul character (terminator) */
                *dst = *src; /* copy the char at 'src' to char at 'dst' (both pointers) */ 
                src += 1;    /* increment src pointer to next char */
                dst += 1;    /* increment dst pointer to next char */
        }
}
Enter fullscreen mode Exit fullscreen mode

It's really not something to make a habit of but in this specific context, C string copying, it's a common idiom.

Haha, I don't think I'll be learning C in this life, but I'm surprised by people who have the strength to learn it. Kudos.

Fair enough! I learnt it years ago downporting a little C++ game for practice and finding that it forced me to write simpler and more to-the-point code. Essentially: data-oriented programming. Those concepts are useful in other languages too!

Great! If you know C I would bet that you know a few other languages.

Speaking of debuggers, I like typing debugger; statements into JS/TS code while debugging. They cause the debugger to break much more reliably (sometimes an issue with TS), are easy to find, and they move with the code as I make changes. I can't remember ever seeing anyone else type enter a debugger; statement into their code.

Oh yes that's very useful! I do it sometimes. Usually it's easier to just click the line in the debugger but with JavaScript it can be a chore to find it in the inspector. Then adding a 'debugger;' line can be helpful.

  • In early days of coding used to put lots of print statements like print(100, value) .... print(200, value) instead of using the debugger.
  • I like pretty printing JSON in terminal.
  • If I have 10 files to commit, I will do git diff on each file and observe the changes before committing.

I feel like print statements are great for debugging, they're good at showing the order of things or changes over time.

For git, try git add -p. Lets you review and stage one change at a time. Or just git diff (for unstaged changes) or git diff --cached (for staged changes), then you don't need to run 10 diff commands in sequence.

I use <big> and <b> tags in HTML to highlight a paragraph between other paragraphs:

<p>This is a simple paragraph.</p>
<p><big><b>This is a highlighted paragraph.</b></big></p>
Enter fullscreen mode Exit fullscreen mode

India's Hindi Film Industry's one of the legendary actors Amitabh Bachchan is also known as "Big B". (However, I am not a fan of him, I just use these tags when defining a class in a CSS file is "costlier". (When such text is written only one or two times.) (I know that <big> tag is deprecated. But it is still working in web browsers, and it is never going away (from how much I know HTML and the web browsers 😄). And even if it is removed, it isn't significant and it will not produce any error, it will simply be ignored by the browsers.)

When writing C, I declare my variables at the start of the function like it's 1989. I just like that separation between storage and logic.
