In JavaScript, you can use the sort() method to sort the elements of an array. By default, the sort() method sorts the elements in ascending order, but you can also provide a custom sorting function to specify a different sort order.
Here is an example of how to use the sort() method to sort an array of numbers in ascending order:
let numbers = [3, 1, 2];
numbers.sort();
console.log(numbers); // Output: [1, 2, 3]{codeBox}
You can also use the sort() method to sort an array of strings in alphabetical order:
let words = ['cat', 'apple', 'dog'];words.sort();console.log(words); // Output: ['apple', 'cat', 'dog']{codeBox}
If you want to sort the array in descending order, you can provide a custom sorting function that compares the elements and returns a value less than 0 if the first element should come before the second element, a value greater than 0 if the first element should come after the second element, and 0 if the elements are equal.
Here is an example of how to use a custom sorting function to sort an array of numbers in descending order:
let numbers = [3, 1, 2];numbers.sort(function(a, b) {return b - a;});console.log(numbers); // Output: [3, 2, 1]{codeBox}
