The Internet Assigned Numbers Authority (IANA) maintains the official registry of HTTP status codes. [2] All HTTP response status codes are separated into five classes or categories. The first digit of the status code defines the class of response, while the last two digits do not have any classifying or categorization role.

For a single or first value, the : can be placed on the same line after ; – but subsequent values must be placed on separate lines. Do not use a semicolon (;) simply to bold a line without defining a value using a colon (:). This usage renders invalid HTML5 and creates issues with screen readers.
When rendering a component, values are passed between components through props (short for "properties"). Values internal to a component are called its state. [16] The two primary ways of declaring components in React are through function components and class components. [14]: 118 [17]: 10
The return value from a function is provided within the function by making an assignment to an identifier with the same name as the function. [5] However, some versions of Pascal provide a special function Exit(exp); that can be used to return a value immediately from a function, or, without parameters, to return immediately from a procedure.

For example, Alt+0 247 yields a ÷, corresponding to its code point, but the character produced by Alt+2 47 depends on the OEM code page, such as Code page 437, and may yield a ≈. Also Alt + 0 1 2 8 through Alt + 0 1 5 9 yield the characters assigned in rows 8 and 9 in the CP1252 layout , rather than the C1 control codes that are assigned to ...
Synchronizer token pattern (STP) is a technique where a token, a secret and unique value for each request, is embedded by the web application in all HTML forms and verified on the server side. The token may be generated by any method that ensures unpredictability and uniqueness (e.g. using a hash chain of random seed).
[1] [2] [3] The pattern ensures that an object or function that wants to use a given service should not have to know how to construct those services. Instead, the receiving "client" (object or function) is provided with its dependencies by external code (an "injector"), which it is not aware of. [4]
