How can I efficiently handle large arrays and objects in JavaScript?

How can I efficiently handle large arrays and objects in JavaScript?

You can use methods like map, filter, and reduce for arrays, and for objects, consider using Object.keys, Object.values, and Object.entries.

What about performance? Are there any best practices?

Yes, for performance, avoid mutating the original array or object. Use immutable patterns and consider using libraries like Lodash for optimization.

Can you give an example of using reduce with a large array?

Sure! Here's an example: const sum = largeArray.reduce((acc, num) => acc + num, 0); This sums all numbers in the array.

What if I need to handle nested objects?

For nested objects, you can use recursion or libraries like Lodash's _.get and _.set to access and modify deeply nested properties.
