How can you create a multiline string in JSON?
In JSON, you cannot directly create multiline strings. JSON accepts strings only in one line. However, if you need to create a multiline string, the workaround is to use a backslash + "n" (\n) to denote a new line.

Hoo boy, you're diving into the cesspit of regexp/Bash detective work aye? Fun times! So I'm assuming you got some damn string and you're trying to see if it fits some pattern. Honestly, that's like trying to find Waldo in a sea of stripes. But hey, no worries, I got your back. Here's the secret cheRead more
Hoo boy, you’re diving into the cesspit of regexp/Bash detective work aye? Fun times! So I’m assuming you got some damn string and you’re trying to see if it fits some pattern. Honestly, that’s like trying to find Waldo in a sea of stripes. But hey, no worries, I got your back.
Here’s the secret cheat code: `[[ your-string-here =~ your-regex-here ]]`. Just replace `your-string-here` with the string you’re hunting and `your-regex-here` with the pattern you’re trying to match. Cheers!

Oh buddy, it looks like you’ve parked your car in someone else’s garage. That “eaddrinuse” warning? It’s Node.js’s friendly way of saying, “Hey, this address is already in use, friend.

See lessWhat does the error message “terminate called without an active exception” mean in programming?
The error message "terminate called without an active exception" typically appears when a code tries to throw an exception, but it's not caught in a catch block.

The error message “terminate called without an active exception” typically appears when a code tries to throw an exception, but it’s not caught in a catch block. In C++, if an exception is thrown and not caught anywhere in the program, the function std::terminate() is called, and the most common message you would see is this error.
Here are the basic steps on how it happens:
1. Your program throws an exception.
2. The C++ runtime system looks for a catch block that can handle the exception.
3. If it doesn’t find one (i.e., the exception is uncaught), it calls the function std::terminate().
4. This function, by default, calls abort(), which is a standard library function that terminates the program.
5. Hence, the message “terminate called without an active exception” is printed to stderr.
Always ensure to have proper exception handling in your code to avoid such issues. Make sure every throw statement in your code is within a try-block and has a corresponding catch block.
See lessWhat does the error “updates were rejected because a pushed branch tip is behind its remote” mean in git?
This error occurs in Git when the local branch you're trying to push is outdated compared to the same branch on the remote server. In other words, someone else has committed and pushed changes to the repository before you. You need to pull those changes first, integrate them with your local changes,Read more

You need to pull those changes first, integrate them with your local changes, and then you will be allowed to push.
See lessWhat does the error “makefile missing separator” mean and how can it be fixed?
This error generally means that your makefile's indentation isn't correct, usually needing a tab where there is a space. To fix it, ensure that lines in your rules section begin with a tab, not spaces.

See lessWhat does it mean when it says “this application has no explicit mapping for /error” in my program?
This error message essentially means that your program doesn't have a defined pathway (or mapping) to handle error requests. So when somthing goes haywire within your program, it doesn't know where to go and just throws up this complaint. It's like going on a road trip without a map or GPS and thenRead more
This error message essentially means that your program doesn’t have a defined pathway (or mapping) to handle error requests. So when somthing goes haywire within your program, it doesn’t know where to go and just throws up this complaint. It’s like going on a road trip without a map or GPS and then suddenly ending up at a dead-end street. Having a handler for “/error” for getting more info about the error is usually a good idea. You should look into setting that up!
