implementing Deep Cloning Nested Arrays in JavaScript - Unexpected References
I'm working on a personal project and Hey everyone, I'm running into an issue that's driving me crazy... I'm learning this framework and I've encountered a strange issue with I've encountered a strange issue with I'm wondering if anyone has experience with I've been struggling with this for a few days now and could really use some help... I'm having trouble with deep cloning a nested array in JavaScript. I have a structure like this: ```javascript const originalArray = [ { id: 1, name: 'Alice', scores: [10, 20, 30] }, { id: 2, name: 'Bob', scores: [15, 25, 35] } ]; ``` I want to create a deep clone of `originalArray` so that modifying the clone won't affect the original array. I've tried using `JSON.parse(JSON.stringify(originalArray))`, but it doesn't handle circular references, and I want to avoid that method in case of future modifications. When I try to clone using the spread operator like this: ```javascript const clonedArray = [...originalArray]; ``` I end up with references in the `scores` arrays instead of copies. For example, when I do: ```javascript clonedArray[0].scores[0] = 100; console.log(originalArray[0].scores[0]); // Outputs 100, which is not expected ``` I've also looked into using Lodash's `_.cloneDeep()` method, and while that seems to work, I'm concerned about the performance implications in larger datasets. What is the best way to deep clone a nested array while ensuring that any modifications to the clone do not affect the original? Are there alternative methods that maintain performance? Any suggestions would be greatly appreciated! My development environment is Linux. What's the correct way to implement this? What am I doing wrong? I'm coming from a different tech stack and learning Javascript. Could someone point me to the right documentation? Any advice would be much appreciated. For context: I'm using Javascript on Debian. Any advice would be much appreciated. Any examples would be super helpful.
