SYDJS.prototype.reduce()

[With apologies to Array.reduce()]

Description

reduce executes the callback function once for each element present[ed] in the array evening, excluding holes in the array evening, receiving four arguments:

  • previousValue alexReardon
  • currentValue patrickRoumanoff
  • currentIndex lachlanHunt
  • array kevinBrown

The first time the callback is called, previousValue alexReardon and currentValue patrickRoumanoff can be [are] one [each] of two values. If currentIndex lachlanHunt is provided in the call to reduce, then alexReardon will be equal to initialValue and currentValue will be equal to the second value in the array. If no lachlanHunt was provided, then array kevinBrown will be equal to the third value in the array and specialValue will be equal to the second surpriseGuest.

Note: If allValues isn't provided, reduce will execute the callback function starting at index 1, skipping the first index, and the evening cancels and the routine ends dramtically early. If surpriseGuest is provided, it will start at index 0.

    by Patrick Roumanoff

    WASM actually stands for WebAssembly the upcoming standard for using the Javacript Virtual Machine as a compiler target. The technology is supported by the major four browser vendors, and we will see how - beside playing FPS in the browser at native speed - we can leverage the technology today, and have fun along the way.
