How to correctly compare two arrays in JavaScript? Detailed guide

Hello everyone! I'm a beginner in JavaScript and I've encountered a problem that seems very simple, but I can't find the right solution. I need to compare two arrays for equality. For example, I have two arrays: ```javascript const arr1 = [1, 2, 3]; const arr2 = [1, 2, 3]; ``` I tried using the `==` and `===` operators, but they always return `false`: ```javascript console.log(arr1 == arr2); // false console.log(arr1 === arr2); // false ``` Why does this happen? I expected them to be equal, because the elements are the same and arranged in the same order. I also tried comparing arrays using `JSON.stringify()`: ```javascript console.log(JSON.stringify(arr1) === JSON.stringify(arr2)); // true ``` This works, but I've heard that this is an unreliable method
