| // James' ghetto year-binary-palindrome thing | |
| // Damn it @joemccann https://twitter.com/joemccann/status/550663311478763520 | |
| // Changed from crazy decimal to binary function to .toString(2)on Mike McNally's most excellent tip: https://twitter.com/m5/status/550690684122845185 | |
| // Loop through years, starting at 0 all the way to 2015 (happy new year) | |
| for(var i = 0; i <= 2015; i++){ | |
| // Get it's binary representation (it'll be a string yo) (thank you @m5) | |
| var binaryYear = (i).toString(2); | |
| // Check if odd, make appropriate offset of 0.5 if so | |
| var offset = 0; | |
| if(binaryYear.length%2==1) { | |
| offset = 0.5; // Shock horror | |
| } | |
| // If it's an even, check if everything to left of center character matches the reverse of everything to right of center character | |
| var left = binaryYear.substring(0, (binaryYear.length / 2 ) - offset); | |
| var right = binaryYear.substring((binaryYear.length / 2 ) + offset); | |
| // Reverse and compare, if matches, log that sucker | |
| if (left === (right.split('').reverse().join('')) ) { | |
| console.log( i+" : "+binaryYear ); | |
| } | |
| } |
