Sort a string in JavaScript

In this article, we will try to understand how to sort strings of characters using several different approaches available using JavaScript.

Let us see how to create a string using the syntax provided by JavaScript and thereafter we will see a short example that will help us to understand this syntax clearly.

Following are some of the approaches which will help us to do our task:

• Using sort() function
• Using sort(), localCompare() and join() methods.

Syntax:

let string_name = "";

Now let us have a look over the below-shown example which will explain the above syntax more clearly.

Example: In this example, we will simply create a string and will try to perform some operations on it.

Fruit name is: banana
Character at 4th index is : n

Now let us see our main task which is to sort the string of characters using several approaches available using JavaScript.

Approach 1: Using the sort() function

• In this approach, we will use the split() method in order to convert our string into an array first.
• We will apply the sort() method on that converted array in order to sort the characters alphabetically.
• After sorting the characters alphabetically, we will convert our array back into the string itself using the method called join().

Example:

Sorted String: 
eiopqrtuwy

Approach 2: Using sort(), localCompare() and join() methods

• We will convert a string into an array itself.
• We will use an array for the same, and then we will apply the sort() method which will take two parameters that represent two characters.
• The localCompare() method will compare the two characters and it will be placed first whichever comes first.
• We will apply the join() method which will join all the characters and make the array return to the string itself.

Example:

Sorted String: 
eiopqrtuwy
