Here's the challange: Sort the 'saying2' array, on about line 19, so that the words are listed in length order. The shortest first. Use the 'length' property on the strings in the sort function.
I've tried a few things. This was the "closest", but still far a way from a right answer:
saying2.sort(function (a,b) {
return saying2[a].length-saying2[b].length;
});
//HELP, please

function ( a, b ) {
return a.length - b.length;
}
The in depth explanation of the mechanics of a and b is a little long. But just consider a and b to be the words in the array being compared.

Treehouse TeacherIn this example, the parameters a and b represent the arrays passed to the anonymous function. In other words, you don't access the saying2 array inside the function:
saying2.sort(function (a,b) {
return a.length-b.length;
});
