The other answer already provides the more straighforward solution (push with --delete option). But there's an older syntax that also works: git push <remote-name> :<branch-name> N...
How to verify if a year is leap? Given a numeric value (such as 2023) or some object that represents a date (such as Date, Calendar, LocalDate, etc), how can I do it?
First of all, we need to understand what a JavaScript Date actually is. And surprisingly, it's not exactly a date (at least not in terms of having unique values for day, month, year, hour, minute a...
The standard for multi-line text input is to use a textarea. Don't use input type="text", it won't work. I'm not sure why you don't want to use a textarea, but after reading this answer, I hope you...
According to this answer, Codidact uses highlight.js for syntax highlight, and "support whatever languages are enabled by default in that package". And according to this table (in highlight.js Git...
tl;dr According to the documentation, innerHTML property "gets or sets the HTML or XML markup contained within the element". Basically, "that's all", but let's see it in more detail. It makes...
Before we start, I'd like to be a little bit pedantic regarding 00002451018 being a number. When we talk about numeric types/values, the zeroes at the beginning are irrelevant: 2, 02 and 000002 al...
I can't speak for the people who designed it, but I guess it was made this way because you can merge multiple branches all at once. Let's say I've created multiple branches: C---D => ...
I've created a function that calls scanf passing a void pointer as argument: void read(const char *format, void *p) { scanf(format, p); } And tested it with different types: int n; read...
When using the Array.prototype.sort method, we can pass a compare function as argument. Then, this function can be used to process array's elements, so the comparison is made using some custom crit...
Why object-oriented instead of class-oriented? tl;dr Because you can "do OOP" without classes. Long answer A class is one possible way to implement object oriented programming. But it's n...
To do that, you could change the selector from body to *, as the other answer said. By selecting only body, it won't change child elements that has defined a more specific rule, and that's why you ...
I've kinda found a very limited, not so elegant, far from ideal "solution", using replaceAll: String regex = "(?:([aeiou]+)[0-9]+|([123]+)[a-z]+)\\W+"; System.out.println("ae123.".replaceAll(regex,...
The solution depends on the Java version you're using. First, let's see the solution for earlier versions, that doesn't use SimpleDateFormat. Then we'll see why the problem happens and alternatives...
I'm using SimpleDateFormat to parse a string containing a date/time, but the result has a different date, hour, minute, second and millisecond: SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM...
Matching a valid email address can be as complicated as you want it to be. If you want to be compliant with RFC 5322, the regex will be a monster (see below). But if you want a subset of it, with...
This MDN link might help to explain that: When a function is called as a method of an object, its this is set to the object the method is called on. Which is your first example (calling obj.a())....
I recently suggested an edit to an answer. Basically, I formatted some code, adding code fences around it: But at the "Review suggested edit" page, the differences are not clearly displayed. I...
Checking the list of tags, I noticed that all of the tag wikis are empty, like this: I also noticed that I can't edit those info. Will it be possible for regular users to add tag wikis?1 And if th...
The problem is the fallthrough behaviour of case statements. Basically, once a case's condition is met, all the others after that are also executed. Example: int x = 2; switch (x) { case 1: ...
How does storing replaced strings in the node variable makes a change in the text appearing to the end user? In your case, you're changing the textContent property. When accessed, it returns t...
any DOM "tree" node is actually a "branch" Not exactly. Document Object Model and Nodes According to the MDN documentation, the DOM (Document Object Model) is "the data representation of the...
Does a for...of loop must contain a variable without assignment sign (=) Yes. and why? Because that's the syntax defined by the language specification. The people who defined it decided ...
Yes, it's possible. In a more general way, every recursive algorithm can be converted to an iterative one (and vice-versa). You just need to use a stack. Internally, a recursive function will use...
I wouldn't use grep. As the other answers already said, it's not the right tool for this job. Considering your specific case (fields separated by /), basename is the most straighforward way, as st...
