What is the process of extracting an object value from an array to convert them into elements of a new array?

Suppose I have an array of objects. My goal is to generate a new array that exclusively contains the key values from those objects stored in the initial array. The catch here is that the number of elements in the original array, denoted by x, is uncertain as it depends on user input. Is there a feasible solution? I've experimented with mapping, filtering, and object.values(), but all these methods end up producing an array of objects.

x = [{1: 182}, {2: 912}, {3: 51}, …]
y = [182, 912, 51, ...]

Answer №1

Traverse through the array using Array.flatMap(), and extract an array of values from each object by utilizing Object.values(). The flatMap function will then combine all sub-arrays into a single array.

const collection = [{1: 182}, {2: 912}, {3: 51}]

const output = collection.flatMap(Object.values)

console.log(output)
