I am working with two arrays:
['x', 'y', 'z']
And array 2:
[{ x: 5, y: 10, z: 15, w: 20 }]
Is there a way to merge these two arrays to get the following output:
[{x: 5, y: 10: z: 15}]
I only want the items present in the first array. Any suggestions for an efficient solution?
An example showcasing the use of the reduce method
arr1 = ['a', 'b', 'c', 'e'];
arr2 = [{ a: 1, b: 2, c: 4, d: 5 }];
result = arr1.reduce((acc, key) => [...acc, {[key]: arr2[0][key]}], []);
console.log(result);If a key in the first array is not found in the second array, its value will be set as undefined.
