I am trying to extract the value of data.notes. After implementing the code below, I noticed that the detailsOfCurrentNotes value changes based on the data.notes. Can anyone provide guidance on how to resolve this issue?
notes :Note[]
const detailsOfCurrentNotes = Object.assign({}, data.notes);
//the value of data.notes is being modified
// detailsOfCurrentNotes reflects these modifications as well
To make a deep copy of an object or array that is not circular, you can use this straightforward method:
const copiedNotes = JSON.parse(JSON.stringify(originalData.notes));
When the variable notes is an array, there are a couple of ways to create a shallow copy:
const detailsOfCurrentNotes = Object.assign([], data.notes);
Alternatively, you can use a shorter syntax:
const detailsOfCurrentNotes = [...data.notes];
Both methods achieve the same result of creating a shallow copy of the original array.
