We will build a JavaScript logic to sum similar keys from multiple objects using the reduce method in JavaScript ES6. We have three objects with different values for each key. The desired result is to sum the values for each key. For "apple," we expect 10 + 15 + 12 = 37, and for "banana," we expect 4 + 6 + 8 = 18. The function will use the reduce method with initial empty object and logic to check existing keys before adding values.
