Script Preparation code:
var o = {'ff1234567890121':0, 'ff1234567890122':1, 'ff1234567890123':2, 'ff1234567890124':3, 'ff1234567890125':4}; var a = ['ff1234567890121', 'ff1234567890122', 'ff1234567890123', 'ff1234567890124', 'ff1234567890125']; var s = '-ff1234567890121--ff1234567890122--ff1234567890123--ff1234567890124--ff1234567890125-'; var t = 'ff1234567890124';
Tests:
Array indexOf
var i = a.indexOf(t);
String indexOf
var i = s.indexOf('-' + t + '-');
Object lookup
var i = o[t];
