I have a rather big array in javascript and use function below to pick out values and sum them, works fine in Chrome but nog in IE

var test = checkoutConfig.quoteItemData.reduce((a, v) => a += parseFloat(v.row_weight),0);

There are other questions about this issue, but i can't figure it out...

It is the arrow syntax `=>` that doesn't work in IE – Asons Apr 19 '18 at 06:42

Nope, really nog working in IE 11. Maybe the reduce does, but the total function doesnt – Jilco Tigchelaar Apr 19 '18 at 06:51
@LGSon, that is what i found indeed. But what is the sollotion to that? – Jilco Tigchelaar Apr 19 '18 at 06:52
@JilcoTigchelaar Check the dupe link (or [MDN](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array/reduce))...it uses/shows `function(){...}` instead – Asons Apr 19 '18 at 06:53
var sum = checkoutConfig.quoteItemData.reduce(function (a,v) { return a += parseFloat(v.row_weight); }, 0); – Jilco Tigchelaar Apr 19 '18 at 07:59
