i want to add an object into another object using typescript.
below is data1
data1 = {firstDetails: {...}}
data1 = {
firstDetails: {
id: '1',
name: 'first'
description: 'description'
//other fields,
}
}
and there is data2 like below
data2 {secondDetails: {...}}
const data2 = {
secondDetails: {
id: '1',
items: [],
values: [],
}
}
now i want to remove property id from secondDetails and then take items and values from data2 and add it to data1.
so the expected output is like below
{
firstDetails: {
id: '1',
name: 'first',
description: 'description',
items: [],
values: [],
}
}
i have tried like below,
const formattedData2 = formattedData2.secondDetails;
const without_id = omit(formattedData2, 'id')
data1.firstDetails = Object.assign(data1.firstDetails, without_id);
but this gives error in dat1.firstDetails in the last line. it says variable data has implicitly any type.
could someone help me fix this. how can i put one object into another using typescript. thanks.
Use destructuring with rest on second details. This way, you wont include the id from second
data1 = {
firstDetails: {
id: "1",
name: "first",
description: "description",
},
};
const data2 = {
secondDetails: {
id: "2",
items: [],
values: [],
},
};
const { id, ...restSecondDetails } = data2.secondDetails;
data1.firstDetails = { ...data1.firstDetails, ...restSecondDetails };
console.log(data1)Using spread and delete operator will help you here an example
delete formattedData2.secondDetails.id;
const object = {...data1.firstDetails, ...formattedData2.secondDetails}
If you want to push the property to the first object user;
Object.assign(data1.firstDetails, data2.secondDetails)
There's multiple ways to do this. I wouldn't use delete as this comes with unnecessary overhead.
A simple general way to do this would be as follows
const combinedObject = firstDetails
Object.keys(secondDetails).forEach(key => {
if (key !== 'id') {
combinedObject[key] = secondDetails[key]
}
})
