While you're on, @DynamicSquid, are you interested in looking into this?
Consider a class such as std::string, which has ::length(), and ::size(), wh
DynamicSquid My first thought was function pointers, but they may not be the best option. Then I found this SO answer, but I don't think it's what you need.
What do you need the alias for anyway? If you want to create two functionally equivalent functions, then just have one function call the other function2 years ago
JavaScript's undefined is it's own type, it doesn't have an object wrapper class, so we can't do "object" === typeof new Undefined, but, if you run th
SixBeeps According to the specs, undefined is one of the primitive data types, which is obvious, but it does mean that it is a type.
It's possible that the browser handles undefined as a special internal type to make things easier to work with, but is inaccessible to the standard programmer.
I don't have much time, but take a look through that specification and see if you find anything interesting.2 years ago

Wumi4 I have use cargo before, so I can't help you the problem you have but at least I can help you to use cargo at the basic level.
To install an executable crate, use cargo install
To run your project, use cargo run on the root directory of it.
To build your project into an executable, use cargo build in the root directory, then cd to target/debug/ and you should see your executable with some other stuff in there.
To initialize a new crate, use cargo init

Doing the above I found out that deleting the arrays makes that error go away but instead now it doesn't like the array-type (type-error).

EpicGamer007 i mean, you can try binary search but it will only work on a sorted array. if the array is sorted, there are many methods to search for a value fast, otherwise, you would have to traverse through the array and get a runtime of O(n)2 years ago

fuzzyastrocat Are you looking for all: initial (which would set everything to their initial values) or all: unset (which would un-inherit all default-inherited CSS values)? So you would do

realTronsi I guess pseudo elements behave kind of like a child, so I'm guessing the styling is also being applied on to it. I guess you could always just apply styling to the pseudo element yourself
section::before {
display: block;
content: "This is a pseudo-element, which shouldn't be tied to the actual element.";
color: black;
background: white;
