Using the charAt() method you can get the character at a specified position in a given string. This method returns a new string consisting of the single UTF-16 code unit located at the specified offset in the string.
str.charAt(index)str: This is the string from which you want to retrieve the character.index: This is the index of the character you want to access within the string.
The charAt() method returns the character at the specified index as a string. If the index is out of range (i.e., less than 0 or greater than or equal to the length of the string), it returns an empty string.
JavaScript charAt()
A simple example code gets the character by index.
<!DOCTYPE html>
<html>
<body>
<script>
const string = "Hello World!"
// finding character at index 1
let index1 = string.charAt(1);
console.log("Character at index 1 " , index1);
</script>
</body>
</html> Output:
Without passing the parameter in charAt() will return character at index 0 which is "H". Because if no index value is passed in the charAt() method. The default index value is 0.
If there is no element in the index value the charAt() method returns an empty string
let sentence = "Happy Birthday to you!";
// finding character at index 100
let result = sentence.charAt(100);
console.log(result);
Output: <empty string>
