The `sort()` function is used to sort data within an array or an array of objects.

# Example 1

When you want sort numbers from lowest to highest. It is as easy as just using the `.sort()` function . This is an array of numbers.

``````const num = [1, 2, 3, 4, 5, 6, 7, 8, 9];
const lowToHighNum = num.sort();

// [ 1, 2, 3, 4, 5, 6, 7, 8, 9 ]
``````

When you want to sort the numbers from highest to lowest, make use of an `if` function (also called the ternary operator). If a is bigger than b, return -1. If a is smaller than b, return +1.

`````` const highToLowNum = num.sort((a, b) => {
if (a > b) {
return -1;
}
if (a < b) {
return +1;
}
else {
return 0;
}
});

//  [ 9, 8, 7, 6, 5, 4, 3, 2, 1 ]
``````

# Example 2

When you want to sort a string in an array alphabetically. It is also as easy as just using the `.sort()` function.

``````const letters = ["c", "m", "a", "p", "b", "f"];
const orderLetters = letters.sort();

// [ "a", "b", "c", "f", "m", "p" ]
``````

When you want to sort the array in an achronological manner, use the ternary operator (`if` statement).

``````const orderLetters = letters.sort((a, b) => {
if (a > b) {
return -1;
}
if (a < b) {
return +1;
} else {
return 0;
}
});

// [ "p", "m", "f", "c", "b", "a" ]
``````

# Example 4

When we want to sort an array of objects. Here we have an object of food.

``````const food = [
{ name: "apple", healthy: true },
{ name: "pizza", healthy: false },
{ name: "broccoli", healthy: true },
];
``````

We want to order the food names alphabetically within the array of objects.

``````const orderFood = food.sort((a, b) => {
if (a.name > b.name) {
return +1;
}
if (a.name < b.name) {
return -1;
} else {
return 0;
}
});

// { name: "apple", healthy: true }
// { name: "broccoli", healthy: true }
// { name: "pizza", healthy: false }
``````
