You should not save props into state. It is considered an anti-pattern. For example:
export default class MyComponent extends React.Component {
constructor() {
super();
this.state = {
url: ''
}
this.onChange = this.onChange.bind(this);

Because Regular Expressions can do a lot, it is tempting to use them for the simplest operations. But using a regex engine has a cost in memory and processor usage: you need to compile the expression, store the automaton in memory, initialize it and then feed it with the string to run it.
And there...
If you want to extract something from a webpage (or any representation/programming language), a regex is the wrong tool for the task. You should instead use your language's libraries to achieve the task.
If you want to read HTML, or XML, or JSON, just use the library that parses it properly and ser...

In GSP the <%= %> syntax is rarely used due to the support for GSP expressions.
A GSP expression is similar to a JSP EL expression or a Groovy GString and takes the form ${expr}:
<html>

</html>
However, unlike JSP EL ...
A pointer is declared much like any other variable, except an asterisk (*) is placed between the type and the name of the variable to denote it is a pointer.
int *pointer; /* inside a function, pointer is uninitialized and doesn't point to any valid object yet */
To declare two pointer variables...
The POSIX and C standards explicitly state that using fflush on an input stream is undefined behavior. The fflush is defined only for output streams.

In Haskell, a function that can take other functions as arguments or return functions is called a higher-order function.
The following are all higher-order functions:
map :: (a -> b) -> [a] -> [b]
filter :: (a -> Bool) -> [a] ...
Lets say we have a class Classy that has property Propertua
public class Classy
{
public string Propertua {get; set;}
}
to set Propertua using reflection:
var typeOfClassy = typeof (Classy);
var classy = new Classy();
var prop = typeOfClassy.GetProperty("Propertua");

Every tag has an overview topic. This topic has a special section named "Versions". In that section, different versions can be defined in a table that has that should
have at least 2 columns:
the first one should be the name of the version
the last one should be the release ...
For some tags it makes sense to have multiple version tables. There might be different subsets of a programming language or framework available, say for different device types as in this example.
The different tables should be prefaced with a heading.
