### Answer by Ethan Karla

The sort() method sorts the elements of an array in place and returns the sorted array. The default sort order is ascending, built upon converting the elements into strings. **Syntax**

```
// Functionless
sort()
// Arrow function
sort((firstEl, secondEl) => { ... } )
// Compare function
sort(compareFn)
// Inline compare function
sort(function compareFn(firstEl, secondEl) { ... })
```

**Example:**

```
const fruits = ['BANANA','APLLE','orang','grapes','mango'];
    fruits.sort();
    console.log(fruits);
    // expected output: Array ['Dec', 'Feb', 'Jan', 'March']
const array1 = [54,21,32,5,1,21];
const array=   array1.sort(function(a,b){
    return a-b;
});
    console.log(array);
```
