Starting with Java 21 (I think), they've introduced ignored variables, so you can now actually do this:

try {
    operation();
} catch (Exception _) {
    // nice weather, eh?
}

Edit: forgot that this is about JS lel

Yeah, Python has it as well. I think the only real use of it is code readability since you declare that this variable will never be used.

If your joking yes, if your not Java and Java Script are seperate things.

Actually made this mistake in front of 20 people the other day. Guy at my job mentioned coding in java and I asked if he was doing web dev 🤦

Plenty of java back end web development, so maybe not as embarrassing as you felt?

2

He said "I've been closing in C# and Java for 2 years" and I asked, in front of everyone, "are you doing web dev?" And he just coldly said no

See this could have been fine if I didn't double down and go "then what are you using java for... OH WAIT"

Visual Basic is a beautiful language

I legitimately use this line in one of my scripts because range.find returns an error of the value is not found. The use case is taking a 2d matrix saved as an array, with data collected from multiple excel tabs and rearranging it for a CSV upload into Salesforce. The initial array contains values that the rest of the data does not have, so when I search for a non existent value, I can skip the error.

Of course vba COULD just implement try/catch statements and that'd be so much cleaner, but alas.

Warnings? We’ll come back and address those later. Maybe once we’re feature complete. Or maybe shortly after that.

Meanwhile in another universe one of my biggest win was to introduce this line in our PR validation pipeline.

eslint . --max-warnings 0

In a codebase with a lot of warnings is even better for me to add a disable comments for all the existing warning and then not allow any new one in.

And then each time a part of the code needs to be touched the existing warning there should be solved too.

Several times I've set the max warnings to whatever the current warning count is, and then decreased that over time.

No, > /dev/null 2>&1 is. If try your example but with file instead null, stderr content not in file.

Because x>y not redirect x to y, but duplicate y and set x to y-duplicate. See bash manpage REDIRECTION (your example in that section for what not work).

As i understand, your example set 2 to what 1 is, then set 1 to null. Now 2 not null, but what 1 before.

2

Yes it do, your example do too. But if test thing and replace null with file, suddenly stderr missing. Happen to me, 5h debug session. Hope to help prevent that for other people.

I don't get it. This isn't funny. I wouldn't approve it in merge request. Most wouldn't.

Trying to hide problems and incompetence is the joke. A lot of people don't want problems solved, they just don't want to see them, and will take the easy route. If you just want that, this is the easy route.

Incompetent? Absolutely, that's the joke.

You reached the end
