Imagine I am with an array of objects in this format
"err": [
{
"chk" : true,
"name": "test"
},
{
"chk" :true
"post": "test"
}
]
Is there a way to organize it like this instead:
"err": [
{
"post": "test"
"name": "test"
}
]
I attempted
arr.filter(obj => delete obj.chk);
Although it successfully removes the chk property, how can I merge the two objects together?
If you want to create a new object without the chk property, you can use the Object.assign method:
const err = [
{
"chk" : true,
"name": "test"
},
{
"chk" :true,
"post": "test"
}
];
const newObj = Object.assign({}, ...err);
delete newObj.chk;
console.log([newObj]);Another approach is to destructure chk and use the rest syntax:
const err = [
{
"chk" : true,
"name": "test"
},
{
"chk" :true,
"post": "test"
}
];
const { chk: _, ...newObj } = Object.assign({}, ...err);
console.log([newObj]);Here's a more concise and functional approach:
const mergeObjects = (...objects) => objects.reduce((mergedObj, obj) => ({ ...mergedObj, ...obj }), {});
// Another functional method that deletes properties from an object
const removeProperties = (object, ...propertiesToRemove) => {
propertiesToRemove.forEach((property) => {
delete object[property];
});
return object;
}
// Example of usage:
const mergedObject = mergeObjects(...[{ a: 'A', err: 'X' }, { b: 'B' }], { c: 'C' }, { d: 'D' }, { e: 'E' });
const finalResult = removeProperties(mergedObject, 'e', 'err', 'error');
console.log(finalResult);
