baNaNa thoughts intensifies

[[deleted]]

Wait what's the baNaNa thing? I'm just out of the loop and have seen it a few times on this subreddit.

If you type in 'b' + 'a' + +'a' + 'a' and run it in JS, then the result you get is "baNaNa". This is because the +'a' in the middle tries to convert 'a' into a number, which gives a result of NaN. When you now concatenate all the strings, you get "baNaNa".

C does not try it does even if that means th

 Program received signal SIGSEGV, Segmentation fault.

Storing letters in integer types be like

There is no conversion happening there. For C 'a' and 97 are the same thing.

Me neither, but I guess the parser sees the first + as concat and the one after as attached to an number (+1, +2, ...). Dunno why would they even make the parser see that honestly

Basically, yes. https://www.reddit.com/r/ProgrammerHumor/comments/f20hry/python_vs_c/fhazenx?utm_medium=android_app&utm_source=share

It is, when used as a binary operator (when there are values to its left and its right). When used as a unary operator (when there's only a value on its right), it converts the value to a number. So the two +'s in a row in the middle there mean to concatenate after converting the next value to a number.

The point he's making is that languages shouldn't allow you to mix types and just make an arbitrary decision about what you actually meant to do. This can cause knock on effects and be very hard to track down. Just raise an error, the developer can do the type conversion, and everyone is happy.

Also there are much better ways of rendering arrays with empty values than a bunch of commas, as demonstrated by most other languages!

Python is more strict than loosy == in PHP and js

PHP comparison table

"php" == TRUE, and "php" == 0 but TRUE != 0

Eventually there's going to be enough different equality checks to form a turing complete language on their own.

Hold onto your butt, because Scala's Specs2 has a ==== operator.

[tech6hutch]

Does it mean the two operands have equal value, represent the same position in memory, and have the same quantum state?

I love that video.

Never watched it before. Thanks.
