JavaScript



'' == '0' //false

0 == '' //true

0 == '0' //true

false == 'false' //false

false == '0' //true

false == undefined //false

false == null //false

null == undefined //true



" \t\r\n" == 0 // true

Math.min() < Math.max(); // false

",,," == Array((null,'cool',false,NaN,4)); // true



new Array([],null,undefined,null) == ",,,"; // true





Math.max(); // -Infinity

Math.min(); // Infinity





var foo = [0];

foo == foo  // true

foo == !foo // true







function toInt(number) {return number && + number | 0 || 0;}

toInt("1");  // 1

toInt("1.2");  // 1

toInt("-1.2");  // -1

toInt(1.2);  // 1

toInt(0);  // 0

toInt("0");  // 0

toInt(Number.NaN);  // 0

toInt(1/0);  // 0





[] + [] // ""  (array plus array equals empty string)

[] + {} // [object Object]

{} + [] // 0

{} + {} // NaN

"S" - 1 // NaN

Buddy, that entire wall of shit makes sense if you understand the language. If you need exactitude, ===, problem solved.

And you'd have to be a moron to do a naive comparison on array or object datatypes and expect it to magically give you back what you "really want".

How could you forget that NaN is not equal to itself?
