Tweet For Code #4

You don't need a thousand lines of code to make a big difference in any coding language.  Oftentimes it's quite the opposite:  a few tiny code snippets can do a world of good and accomplish big things.  I asked my Twitter followers to tweet to me their favorite tiny snippets of code -- that's a bit difference to try to pack into 140 characters!  Here are my favorites from this round!

ES6 Array Initialization

Here are a few clever ways to initialize an array with ES6:

@davidwalshblog Initialize an array with a default value (#ES6): > Array.from({ length: 7 }, _ => 42); [42, 42, 42, 42, 42, 42, 42]

— Jeremy Martin (@jmar777) November 12, 2014

@davidwalshblog Similarly, initialize w/ 1-N: > var oneToN = n => Array.from({ length: n }, (_, i) => i + 1); > oneToN(5); [1, 2, 3, 4, 5]

Short syntax for dynamic result!

Remove Wrapping HTML with inner/outerHTML

This neat little trick allows you to remove a wrapping element and re-parent the child in one operation.

@davidwalshblog `elem.outerHTML = elem.innerHTML;` removes wrapping `elem`.

Of course you would brick your event connections but this is a neat trick.

3D Body Elements

Want a 3D look at a page's elements?  Check out this sweet JavaScript snippet:

@davidwalshblog t='transform';$('body').css({perspective:999}).css(t,'preserve-3d').children().css(t,'translateZ(-500px) rotateY(30deg)');

This is a really neat optical effect, though not the most practical of snippets.

YOLO!

Since `sudo` gives you the ultimate of powers, why not give it a YOLO alias?

@davidwalshblog `alias yolo= 'sudo'` is always fun

Hilarious!

Thank you to everyone who participated, and keep your tiny snippets for the next Tweet for Code!
