Here is an array of objects:
let array = [{ firstName: "John", lastName : "Doe", id:5566, weight: 70 },{ firstName: "Francis", lastName : "Max", id:5567, weight: 85 }];
I am looking to remove the properties "lastName" and "weight" for all objects in this array. Any suggestions on how to achieve this?
If you want to utilize .map() with Object Destructuring and the rest parameter syntax, here's how you can do it:
let details = [
{firstName: "John", lastName: "Doe", id:5566, weight: 70 },
{firstName: "Francis", lastName: "Max", id:5567, weight: 85 }
];
let outcome = details.map(({ lastName, weight, ...remaining}) => remaining);
console.log(outcome);.as-console-wrapper { max-height: 100% !important; top: 0; }Sources:
updatedArray = array.map(individual => ({ firstName: individual.firstName, id: individual.id }))
It's been a while since I've used map, but I think that should work
Give this a shot:
for(let i = 0; i < array.length; i++) {
array[i] = {
id: array[i].id,
firstName: array[i].firstName
}
}
This code snippet essentially creates new objects in the array with only the specified properties.
