The first array has the actual property while the second one has the value property.第一个数组具有actual属性，而第二个数组具有value属性。 I would like this merge it into one.我想把它合二为一。

I want to merge the properties based on each parent so my expected output looks something like this :我想合并基于每个父级的属性，因此我的预期输出如下所示：

{"name":"Eraser","value":"2110.99","actual":"498573.6182"}
