how to get array according to conditions in javascript

Question

My array comes like this

var data=[{PRODUCT : P1}, {PRODUCT: P2}]

I wantt to convert this into [P1, P2]. Sometimes my array comes like this

var data=[{ITEM: I1, QUANTITY:1}, {ITEM: I2, QUANTITY:2}]

I wantt to convert this into [I1, I2].

so can we make a common function, where I just want to extract particular value of array and make a new array. p.s. Thank you in advance

---

I tried to write the logic like this:

data.map((d, index) => { var result= [];
               result.includes(d[0]); })

but it,s not dynamic

Answer 1

you can iterate through your array with map() method and inside it extract the value of a first entity of an object in your array and simply get a new array with all values:

const data1 =[{PRODUCT : 'P1'}, {PRODUCT: 'P2'}]
const data2 = [{ITEM: 'I1', QUANTITY: 1}, {ITEM: 'I2', QUANTITY: 2 }]
const transformValuesOfArray = (arrayToTransform) => 
arrayToTransform.map(value => {
 const firstObjectValue = Object.values(value)[0]
 return firstObjectValue
})
console.log(transformValuesOfArray(data1))
console.log(transformValuesOfArray(data2))
