// THE PROBLEM:
const firstArray = ["cookies", "milk", "chocolate"]
const secondArray = ["cookies", "milk", "chocolate"]
console.log(firstArray == secondArray) // always returns FALSE

// THE SOLUTION:
if(JSON.stringify(firstArray) === JSON.stringify(secondArray)){
  console.log("firstArray is the same as the secondArray")
} else {
  console.log("firstArray is different from the secondArray")
}

How to compare arrays in JavaScript?

Comment

// Warn if overriding existing method
if(Array.prototype.equals)
    console.warn("Overriding existing Array.prototype.equals. Possible causes: New API defines the method, there's a framework conflict or you've got double inclusions in your code.");
// attach the .equals method to Array's prototype to call it on any array
Array.prototype.equals = function (array) {
    // if the other array is a falsy value, return
    if (!array)
        return false;

    // compare lengths - can save a lot of time 
    if (this.length != array.length)
        return false;

    for (var i = 0, l=this.length; i < l; i++) {
        // Check if we have nested arrays
        if (this[i] instanceof Array && array[i] instanceof Array) {
            // recurse into the nested arrays
            if (!this[i].equals(array[i]))
                return false;       
        }           
        else if (this[i] != array[i]) { 
            // Warning - two different object instances will never be equal: {x:20} != {x:20}
            return false;   
        }           
    }       
    return true;
}
// Hide method from for-in loops
Object.defineProperty(Array.prototype, "equals", {enumerable: false});
