How to Retrieve Only a Single Value from an Array Using JavaScript

Here is an example array:

data:[
{key: "1", value: "a"},
{key: "2", value: "b"},
{key: "3", value: "c"}]

I need help transforming the array into this format:

data:{"1","a","2","b","3","c"}

Answer №1

Transforms key value pairs into a single object map. It seems like this is the desired outcome.

data = [
{key: "1", value: "a"},
{key: "2", value: "b"},
{key: "3", value: "c"}]
data=Object.fromEntries(data.map(({key, value})=>[key,value]))
console.log(data)
console.log(data["2"])

Alternatively, if you prefer only values in an array:

data = [
{key: "1", value: "a"},
{key: "2", value: "b"},
{key: "3", value: "c"}]
data=data.map(({value})=>value)
console.log(data)

Answer №2

To achieve the desired result, you can utilize both the flatMap and Object.values. Just a heads-up, the expected output appears to be an invalid object; assuming you intended it to be in array form instead.

data = [
{key: "1", value: "a"},
{key: "2", value: "b"},
{key: "3", value: "c"}]

const output = data.flatMap(Object.values);

console.log(output)
