ViewsHow to convert a specific element in an array to number?
I want to convert the fileID that is in the current array from string to number, e.g: fileID: "1" to fileID: 1.
How to target the specific item (fileID) so that I can convert it to a number and map the current array into a new array?
Current array:
[
{
fileID: "1",
fileName: "Cardio Care Awareness Month",
createdByID: "100101"
},
{
fileID: "2",
fileName: "MEMO COMPULSORY TO",
createdByID: "100101"
},
{
fileID: "3",
fileName: "MEMO 2021 Covid19 Vaccination Leave",
createdByID: "200201"
},
{
fileID: "4",
fileName: "Human Cell",
createdByID: "200201"
}
]
New converted array:
[
{
fileID: 1,
fileName: "Cardio Care Awareness Month",
createdByID: "100101"
},
{
fileID: 2,
fileName: "MEMO COMPULSORY TO",
createdByID: "100101"
},
{
fileID: 3,
fileName: "MEMO 2021 Covid19 Vaccination Leave",
createdByID: "200201"
},
{
fileID: 4,
fileName: "Human Cell",
createdByID: "200201"
}
]

Here is a function that should convert the array into the format you want.
const convertArray = array => array.map(({fileID, ...item}) => ({fileID: Number(fileID), ...item}))

You can create a custom function and re-use it in your application.
Example :
const parseData = (data, key) => {
return data.map(item => {
return {
...item,
[key] : Number(item[key])
}
})
}
parseData(data, 'fileID')
0: {fileID: 1, fileName: 'Cardio Care Awareness Month', createdByID: '100101'}
1: {fileID: 2, fileName: 'MEMO COMPULSORY TO', createdByID: '100101'}
2: {fileID: 3, fileName: 'MEMO 2021 Covid19 Vaccination Leave', createdByID: '200201'}
3: {fileID: 4, fileName: 'Human Cell', createdByID: '200201'}
