React creates an in-memory data-structure cache, computes the resulting differences, and then updates the browser's displayed DOM efficiently. [31] This process is called reconciliation. This allows the programmer to write code as if the entire page is rendered on each change, while React only renders the components that actually change.
After the first page load, all subsequent page and content changes are handled internally by the application, which should simply call a function to update the analytics package. Failing to call such a function, the browser never triggers a new page load, nothing gets added to the browser history, and the analytics package has no idea who is ...
Whole references may be transcluded from other pages. When the "Edit" or "Edit source" tab at top of a page is clicked, the bottom of the window will say "Pages transcluded onto the current version of this page". Click the text if no list is shown. Articles are more likely than other pages to contain named references.
Unit is defined as a single behaviour exhibited by the system under test (SUT), usually corresponding to a requirement [definition needed].While it may imply that it is a function or a module (in procedural programming) or a method or a class (in object-oriented programming) it does not mean functions/methods, modules or classes always correspond to units.
Pages in the page cache modified after being brought in are called dirty pages. [5] Since non-dirty pages in the page cache have identical copies in secondary storage (e.g. hard disk drive or solid-state drive), discarding and reusing their space is much quicker than paging out application memory, and is often preferred over flushing the dirty pages into secondary storage and reusing their space.
Determine whether a stolen page frame still contains an unmodified copy of the page; if so, use that page frame. Otherwise, obtain an empty page frame in RAM to use as a container for the data, and: Determine whether the page was ever initialized; If so determine the location of the data on disk. Load the required data into the available page ...

A double-click is the act of pressing a computer mouse button twice quickly without moving the mouse. Double-clicking allows two different actions to be associated with the same mouse button. It was developed by Tim Mott of Xerox Palo Alto Research Center.
