Answer 1

then use this

$('.loincode').each(function( index ) {
    $(this).attr("checked",(data.loin && data.loin.filter(x=>(x==$(this).val())).length) ? true : false);
});

 var data={loin:["108591","108592"]} $('.loincode').each(function( index ) { $(this).attr("checked",(data.loin && data.loin.filter(x=>(x==$(this).val())).length)? true: false); });

 <script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script> <input type="checkbox" class="loincode" value="108591" /> <input type="checkbox" class="loincode" value="108592" /> <input type="checkbox" class="loincode" value="108593" />
