Ten years into casual programming and I still don’t know how to use a debugger.
I believe in a conspiracy theory that nobody uses debuggers.
console.logcounts as “a debugger”, right?It does for me!
Yes, but only because it gives you a link to where that was run. Click the link to the right with filename:lineNumber, and it will open the sources tab to that line. Set a breakpoint and rerun to pause there, then step through the code’s execution.
Of course, if you’re using minified or processed code, this will be more difficult, in that case figure out how to do it in VS Code.
I use them daily. It makes it so much easier to work with an existing code base
Yep. Once you get the hang of it, you will cringe to think of all the wasted effort that came before. But getting the hang of it takes dedication.
It’s easy, you just step, step, step, step in, or wait, over, or, oops.
Watch a Video or read something because it really is an invaluable tool. But here’s a crash course:
Debuggers, or IDEs, let you step through your code in slo-mo so you can see what is happening.
- Set a breakpoint - Click to the left of a line of code so a red dot appears. Run your program, and the IDE will execute to that line, then pause.
- Look at variables’ values - While the execution is paused you can hover over variables before that line to see their value.
- Step through the code - See what happens next in slo-mo.
- Use “Step Into” to enter into a function and see what that code does.
- Use “Step Over” to not go into a function and continue in the current spot after the function has done its business.
- Use “Step Out” to exit a function and pick up the execution after it has run. Use this when you’re in too deep and the code stops making sense.
- See whats in the heap - The heap will list all the functions that you’re currently inside of. You can jump to any of those points by clicking them.
- Set a watch - Keep a variable in the watch so you can see what its value is at all times.
- Set a condition on the breakpoint - If the breakpoint is inside a big loop, you can right-click on the red dot to create a conditional breakpoint, so you write something like x===3 and it will only pause when x is 3.
There are many other things an IDE can do to help you, so def look into it more if you want to save yourself a lot of insanity. But this is a good starting point.
If you’re developing for the web use F12 to open web tools, and when an error happens, click the file/line number to see that point in the Sources tab, and you can debug there.
Thank you for writing this out
Good my colleagues think I am Hackerman that can hack through time!
That image goes so incredibly hard
Dude, literally me. Whenever my friends or my brother’s friend come to my room, I opened up a few terminals with only one of them is actually for coding and they thoight I could hack someone’s Facebook account or something LMAO.
Yes I live in Southeast Asia

Father, I want to see the face of VBA god

I identify with Samir, but without all of his vast knowledge.
Samir is mad op, those indian youtubers know everything
What I want to know is who taught the original Indian YouTube tutor. Was he born with the knowledge?
The goddess Namagiri.
Om Namo Namagiriyai Namah, must be the mantra to be a successful programmer then I guess.
I’m Samir, I can code kernel drivers in vba
Please don’t.
I can but then I have to call IT to start Excel with elevated privileges so I don’t
“Can reveal the face of God using VBA”
This one got me good. I became a VBA king being in one of those locked down environments.
Ok, so, I thought I was crazy when I said “debug it” and my coworkers were like “you can read that shit?”
My colleague literally once said to me “i can’t read bleep bloops”
Heck I remember when you had to read “bleep bloops”. POST codes came in beeps, and that’s how you knew why the computer wouldn’t start.
Sometimes I miss em, wish it gave those in addition to the modern indicators. Then I could just tell without even looking.
I have worked with most of these people at one point or another. I used to sit next to an old architect like walters. He had so many patents the company only recognize him on every 10th one.
I can really emphasise with Samir. Working in healthcare I’m basically limited to just the Office applications. However in the past few years I’ve been able to cook up solutions by reading / writing to file based databases, and using VBA to generate and bind to HTML contents on the fly for the built in IE11 instance. It’s as close to getting to some kind of web-stack within the confines of IT Sec in healthcare.
Just a heads up, I think the word you’re looking for is empathize.
OMG, of all the memes I read all day long, this had to be the one to actually make laugh hard.

I’m in this picture and I like it. I’m wjhbr.
Ahaha, yes. I lost it and found it hilarious when I got to that part of the picture, then went “Hey wait a second… that’s me!”
