Combine an object of array JS

Question

Object

I have an Object of Arrays like this and I want to combine them(add values to every key )

It's possible to give to every array key: "state" and value: parseFloat(value) or how i can do it?

• evolutionxbox: Use for loop or reduce to add up the values.
• evolutionxbox: Does this answer your question? Sum values of objects in array
• ikhvjs: Isn't the title should be an array of objects?
• StackByMe: Can you please update your question with the expected output and the attempt(s) you made of solving the problem? This way we can help you understand the issue better

Answer 1

You can save yourself some typing, and provide some future-proofing in case you later need to handle a different set of territories, by getting the keys from the object itself, and then iterating over those keys:

let val = {};
val = filteredMiles.reduce(
 function (previousValue, currentValue) {
 const keys=Object.keys(previousValue);
 const result={};
 keys.forEach(key=>{
 result[key]= parseFloat(previousValue[key])) 
 +parseFloat(currentvalue[key])
 })
 return result
 };
 });
console.log(val);
