 [

  0:{qty:120}

  1:{qty:110}

  2:{qty:130}

How can I do it?

Answer 1

You can use for loop to compare the object's property one by one.

The following example shows how to find the largest qty :

 var elArr = [{qty:120},{qty:110},{qty:130}]; var largestQty = elArr[0].qty; for(let i = 1; i<elArr.length; i++){ if(elArr[i].qty > largestQty) largestQty = elArr[i].qty; } console.log(largestQty);
