How can I efficiently iterate over all key-value pairs of an object in JavaScript? [closed]

I have an object in JavaScript with multiple key-value pairs, and I need to iterate over all of them to perform some operations. What is the most efficient way to iterate over all key-value pairs of an object in JavaScript?I’ve considered using a for…in loop, Object.keys(), and Object.entries(). Are there any performance differences between these methods, or is there a preferred approach?

Additionally, are there any other methods or libraries that provide better performance or additional functionality for iterating over object properties?
