i noticed that certain code that evaluates some shoe sizes JSON for an e-commerce site and outputs them on screen is messing up the order in chrome. the JOSN string given can be: {"7":["9149","9139","10455","17208"],"7.5":["9140","9150","10456","17209"],"8":["2684","9141","10457","17210"],"8.5":["9142","10444","10458","17211"],"9":["26...
