  2. Help:Switch parser function - Wikipedia

    en.wikipedia.org/wiki/Help:Switch_parser_function

    The switch parser function, coded as "#switch", selects the first matching branch in a list of choices, acting as a case statement. Each branch can be a value , an expression ( calculation ), or a template call, [ 1 ] evaluated and compared to match the value of the switch.

  3. Switch statement - Wikipedia

    en.wikipedia.org/wiki/Switch_statement

    Optimizing compilers such as GCC or Clang may compile a switch statement into either a branch table or a binary search through the values in the cases. [6] A branch table allows the switch statement to determine with a small, constant number of instructions which branch to execute without having to go through a list of comparisons, while a ...

    var x1 = 0; // A global variable, because it is not in any function let x2 = 0; // Also global, this time because it is not in any block function f {var z = 'foxes', r = 'birds'; // 2 local variables m = 'fish'; // global, because it wasn't declared anywhere before function child {var r = 'monkeys'; // This variable is local and does not affect the "birds" r of the parent function. z ...

    To make comparisons based on dates (e.g., if the current date and time is after some other date and time), first convert the time(s) to the number of seconds after January 1, 1970, using the function {{#time: U }}, then compare (or add, subtract, etc.) those numerical values.

    "Mind-reading Monty": The host offers the option to switch in case the guest is determined to stay anyway or in case the guest will switch to a goat. [33] Switching always yields a goat. "Angelic Monty": The host offers the option to switch only when the player has chosen incorrectly. [58] Switching always wins the car.

  7. Relational operator - Wikipedia

    en.wikipedia.org/wiki/Relational_operator

    In JavaScript, PHP, VBScript and a few other dynamically typed languages, the standard equality operator follows so-called loose typing, that is it evaluates to true even if two values are not equal and are of incompatible types, but can be coerced to each other by some set of language-specific rules, making the number 4 compare equal to the ...

    en.wikipedia.org/wiki/ECMAScript

    The ECMAScript specification is a standardized specification of a scripting language developed by Brendan Eich of Netscape; initially named Mocha, then LiveScript, and finally JavaScript. [7] In December 1995, Sun Microsystems and Netscape announced JavaScript in a press release. [ 8 ]

  9. Loop-switch sequence - Wikipedia

    en.wikipedia.org/wiki/Loop-switch_sequence

    The most common example of the correct use of a switch within a loop is an inversion of control such as an event handler. In event handler loops, the sequence of events is not known at compile-time, so the repeated switch is both necessary and correct (see event-driven programming, event loop and event-driven finite state machine).
