I have a set of objects that I want to convert into objects with specific key names, following the format {key}{index)
const input = [
{
item: 'Apple',
amount: '3'
},
{
item: 'Banana',
amount: '5'
},
// ...
]
Here is an illustration of the expected output where each index gets added to the key name resulting in item1, amount1, item2, amount2..
const output = { item1: 'Apple', amount1: 3, item2: 'Banana', amount2: 5 }
Implement the use of reduce:
const updatedData = input.reduce((accumulator, element, position) => {
let {itemData, itemQuantity} = element;
// Adjusting for 0-based index by adding 1
accumulator["itemData" + (position + 1)] = itemData;
accumulator["itemQuantity" + (position + 1)] = itemQuantity;
return accumulator;
}, {});
Give this a shot:
const transformedResult = input.reduce((acc, item, index) => {
Object.keys(item)
.forEach(key=>{
acc[key+(index+1)] = item[key]
})
return acc;
}, {});
