How can I compare two arrays in JavaScript?

You can compare two arrays in JavaScript by checking if they have the same length and then comparing each element.

What if the arrays contain objects?

If the arrays contain objects, you can use a function to compare the properties of the objects in each array.

Can you show me an example of comparing arrays with objects?

Sure! You can use the JSON.stringify() method to compare objects. Here's a simple example:

const array1 = [{ id: 1 }, { id: 2 }];
const array2 = [{ id: 1 }, { id: 2 }];

const areEqual = JSON.stringify(array1) === JSON.stringify(array2);
console.log(areEqual); // true
