How Can I Combine JavaScript Objects Based on Shared IDs?

Combining Objects Based on Shared IDs in JavaScript

The task of merging two arrays and combining objects based on a shared "id" field is encountered frequently in JavaScript programming. To achieve this, we can utilize ES6 features to create a concise and efficient solution.

One approach involves mapping the elements of the first array and, for each element, searching the second array for an object with a matching "id" value. If a match is found, the properties from both objects are merged using the ES6 spread operator, resulting in a new object that contains all the desired data.

The following code snippet demonstrates this solution:

const a3 = a1.map(t1 => ({ ...t1, ...a2.find(t2 => t2.id === t1.id) }));
