secondGreatLow.js
/* Coderbyte Challenge
Using the JavaScript language, have the function SecondGreatLow(arr) take the array of numbers stored in arr
and return the second lowest and second greatest numbers, respectively, separated by a space.
For example: if arr contains [7, 7, 12, 98, 106] the output should be 12 98.
The array will not be empty and will contain at least 2 numbers.
*/
function SecondGreatLow(arr) {
var secLowest,
secHighest;
//sort it up
arr.sort(function(a, b) {
return a - b ;
});
//grab the vals
secLowest = arr[1];
secHighest = arr[arr.length-2];
//send em back
return seclowest + ' ' +secHighest;
}
// keep this function call here
// to see how to enter arguments in JavaScript scroll down
SecondGreatLow([4, 90]);

how do you resolve for situations as in the example, where the 7 is repeated twice, and you have to capture 12 in your answer?

@Shahab0622 his code did not generate unique values. You can use a for loop to find unique values or define a function (see discussion on Stack Overflow http://stackoverflow.com/questions/1960473/unique-values-in-an-array/14438954#14438954).
