Why is Ellen Facing such Criticism?

DeGeneres reportedly tweeted:
"Go USA! Fastest goal in U.S World Cup History in the #USAvsGhana game. 32 seconds! It took me longer to look up where Ghana is." 

Ellen's not new to controversy. Shes been all over the headlines because of facelift rumors. 
What do you think?

heh awesom exploit, it's pretty much mine (n===+n to check for numeric, n|0 to round), but with built-in operators. funky   Claudiu Oct 7 '10 at 21:11

@John Hartsock a string is never going to be a numeric value. It's a string. The point of this function is to test whether a value is a Javascript numeric value that has no fractional part and is within the size limits of what can be represented as an exact integer. If you want to check a string to see if it contains a sequence of characters that represent a number, you'd call parseFloat() first.   Pointy Oct 7 '10 at 21:23
  	  	
@Pointy but parseFloat("1.1a") will still return 1.1. Suppose you had a text field you wanted to validate that it was an float and only a float without alpha characters. Testing weather a text field from an input element for decimal(float)   John Hartsock Oct 7 '10 at 21:28

@John Hartsock: it won't return true unless a number primitive was passed. I think that makes sense given the names of the functions. Anything else should be a candidate for isString, isBoolean, etc. if such functions are being written.   Dagg Nabbit Oct 8 '10 at 2:43

@Pointy: double precision floats can represent integer values exactly up to 2^53. So it depends if the OP was asking about integer in the maths sense (whole numbers) or in the 32-bit data sense. If it's the latter, your solution is perfect.   Dave Feb 18 '12 at 1:26
  	  	
@Dave yes that's true, but note that when JavaScript wants to deal with integers it usually bashes them down to 32 bits.   Pointy Feb 18 '12 at 2:57

+1 for using n|0 to convert the value to a signed 32-bit integer. As @Dave says, the integers between 2^31 and 2^53 are interesting in JavaScript, because they can be represented exactly, but get truncated to their least-significant 32 bits by the bitwise operators.

@DaggNabbit I've never seen ===+ or | in JavaScript before. I understand what @Claudiu said about them but I don't see them mentioned anywhere on w3school. Is there a place I can go to see some documentation on them? I'm going to guess | is a bit wise operator, is that right? Is ===+ some kind of addition or maybe its a positive sign operator which would only work on a number? Again I can't find anything about these anywhere. Thanks.   Dan Oct 23 '13 at 21:38

@Dan: ===+ is actually two operators, === (strict equality), and then unary +, e.g. (+5). the | is bit-wise or, yes.   Claudiu Oct 23 '13 at 21:41

@Dan, Claudiu is right, ===+ was just my lazy formatting. It's fixed now, with Pointy's excellent comment added. Also, w3schools is generally considered to be inaccurate and incomplete; you probably don't want to use it for a reference. Better to stick to docs from MDN, WHATWG, W3C, and the official spec.   Dagg Nabbit Oct 23 '13 at 23:59
  	  	
The only caveat with this method is that bitwise operators in JavaScript work up until 32 bits, so large numbers will give false as an integer.   Gastn Snchez Apr 2 at 15:26
  	  	
@GastnSnchez ISTM if a number cannot be expressed as an unsigned 32-bit int, it is not an "integer" in the context of JavaScript. IOW the only way this question is useful is if it's asking how to identify numbers that can be converted to the format required by bitwise operators without changing their value. Determining whether a number has no fractional part is trivial; I assume that's not what was being asked here.   Dagg Nabbit May 1 at 2:00
