It is very simple to sort in JS. Just use the .sort() method. But there are a few important things to know and be aware of:

Sorting a-z, just use .sort():

        word_array = [
        "animal",
        "phone",
        "water",
        "computer",
        "bottle",
        ];
        console.log(word_array.sort()); // (5) ["animal", "bottle", "computer", "phone", "water"]

However, if you use .sort() on an array of numbers it will not sort it correctly:

        num_array = [
            1000,
            200,
            22,
            2,
            102,
            199,
            150,
            100000,
            2.24,
        ];
        console.log(num_array.sort()); //(9) [1000, 100000, 102, 150, 199, 2, 2.24, 200, 22]

The output from this - [1000, 100000, 102, 150, 199, 2, 2.24, 200, 22] is clearly not sorted propperly. It sorted it by comparing character by character, as if it was a string comparison.

You can fix this by providing a comparison function to sort, like this:

        num_array = [
            1000,
            200,
            22,
            2,
            102,
            199,
            150,
            100000,
            2.24,
        ];
        console.log(num_array.sort(function(a,b) { return a-b; }));

And this will now output the correctly sorted array: [2, 2.24, 22, 102, 150, 199, 200, 1000, 100000]
