console. log (a || b); // if a is true, return a, otherwise return b console. log (a && b); // if a is false, return a, otherwise return b Programmers who are more familiar with the behavior in C might find this feature surprising, but it allows for a more concise expression of patterns like null coalescing :
Diagram of a double POST problem encountered in user agents. Diagram of the double POST problem above being solved by PRG. Post/Redirect/Get (PRG) is a web development design pattern that lets the page shown after a form submission be reloaded, shared, or bookmarked without ill effects, such as submitting the form another time.
In Unix-like operating systems, true and false are commands whose only function is to always return with a predetermined exit status.Programmers and scripts often use the exit status of a command to assess success (exit status zero) or failure (non-zero) of the command.
To activate the Javascript, the wikipage must be loaded with a withJS= parameter. The Javascript code has been tested with the Firefox 10.0 browser so far. It makes some use of the jQuery library, which is commonly used in Wikipedia scripts. Data used during the input and upload process are stored in a Javascript object named window.fuw.
The value range form is as follows: for i from f by b to t while w do # loop body od; All parts except do and od are optional. The for I part, if present, must come first. The remaining parts (from f, by b, to t, while w) can appear in any order. Iterating over a container is done using this form of loop: for e in c while w do # loop body od;
In some programming language environments (at least one proprietary Lisp implementation, for example), [citation needed] the value used as the null pointer (called nil in Lisp) may actually be a pointer to a block of internal data useful to the implementation (but not explicitly reachable from user programs), thus allowing the same register to be used as a useful constant and a quick way of ...
Entertainment Merchants Association—which challenged a California law restricting the sale of "violent video games" (defined using a variation of the Miller test separate from ratings assigned by bodies such as the ESRB) to minors, insisting that video games were considered a protected form of expression under the First Amendment, meaning ...
