fruit = [ "orange", "pineapple", "apple" ];
writeOutput( fruit.find( "apple" ) );

Using arrayFind with a closure / callback function

The arrayFind function passes each array value into the supplied function. The function returns a boolean, true if you found what you are looking for. The result of the arrayFind function is the index of the array element that was found, or 0 if not found.

a = [5,4,3,2,1];
writeOutput(arrayFind(a, function(item) { return item == 2;}));
