A: What is the main difference between event delegation to other event handling patterns in JavaScript? tl;dr The purpose of `addEventListener` is to define what happens when an event is triggered at some element. But it also allows us to implement event delegation, due to the bubbling/propagation behaviour. Explaining the terminology Bubbling Suppose I have this HTML: ```html A par... (more) |

Please take this as constructive criticism. If you want to create a programming language, perhaps you should go back a few steps and first study some relevant topics such as parsers/lexers, [BNF](https://en.wikipedia.org/wiki/Backus%E2%80%93Naur_form), grammars, etc. To start with a simple parser/lex...

A: Why is the switch statement not executing the correct case blocks? 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: ```java int x = 2; switch (x) { case 1: System.out.println("one"); case 2: System.out.println("two"); ... (more) |

`open` accepts only one URL. You'll probably have to add a callback after the first request is finished:
```javascript
ajax.onload = function () {
// Request finished, make another AJAX call here
var anotherAjax = new XMLHttpRequest();
// anotherAjax.open, send, etc...
};
ajax.send... (more) |

A: What are the disadvantages of using static methods in Java? > Is it better to use static method? I don't like to think of `static` (or any other language feature/mechanism) in terms of bad/worse and good/better (although I do that too, I constantly try to avoid it). What I usually try/prefer to do is to understand how something works, why it exists, the... (more) |

@#54212 Less code != better. Just because you typed less characters, it doesn't necessarily mean it's "better" (BTW, most IDE's can autocomplete the imports for you, which makes this point even more irrelevant, IMO). What you should seek is clear, concise, semantic and correct code, regardless of its... (more) |

A: How to run a remote JavaScript file from GitHub? As you're using userscripts, I'm assuming this code is supposed to run in a browser. Hence, you could download the scripts and add its contents to the page's DOM (by using a `script` element). For that, you can use the Fetch API: ```javascript fetch('http://your.script.url', { cache: "no-store... (more) |

A simple approach is to have a dictionary (so you store as `vars['x'] = x_value`). Of course this doesn't handle different scopes, but for a very simple interpreter, it's a starting point...
As a side note, this has absolutely nothing to do with being OOP or not. (more) |

A: How to make the text box such that its placeholder goes up and arranges itself in the centre of the border upon clicking? The basic ideia is to create an `input` with a "fake" placeholder, and a `span` that will serve as the actual placeholder text. Then you group both inside a `label`, like this: ```html Enter your password ``` Note the `input`'s "fake" placeholder (just a single space). We'll use it ... (more) |

A: What input functions can I use in TIO's PHP? You could use `fgets` to read from `STDIN`. And to print the message, just use the short tag (``): ```php Try it online! Of course you could also do: ```php <?php echo 'Hello, '.fgets(STDIN).'!'; ``` And there are also other functions you could use, such as `filegetcontents("php://... (more) |

Regarding warnings, they're usually meant to tell you "*Hey, there's something strange here, you should take a look*". You shouldn't ignore them, unless there's a very good reason - which is not the case of your code, IMO.

Yes, it can crash, because this leads to undefined behaviour. Try to search for a number that's not in the array, what will it return? I've tested in a Ubuntu machine, with g++ (it returns `6`) and clang++ (*Illegal instruction* error), but as all undefined behaviours, this can vary a lot. IMO, you s... (more) |

Although it "works", it's not the only solution (and IMO, not even the best - for many reasons that don't fit in this space, I usually don't consider global variables as my first choice). You could pass the variable as an argument to the function, for example (or, depending on what you need, make the... (more) |

Is there a workaround to highlight code blocks if the language doesn't have syntax highlight enabled?

According to the status-deferred tag description: "the requested feature will not be implemented in the near future". From that description, my understanding is that there's not a timel... (more) |

First, let's see the solution for earlier versions, that doesn't use `SimpleDateFormat`. Then we'll see why the problem happens and alternatives for older versions.
