charAt() method returns an empty string.
Here is an example of how the
charAt() method works:
const string1 = 'Hello, world!'; const result = string1.charAt(7); // the result will be: 'w'
In the code example above, we first declare a string called
string1 that contains the text
Hello, world!. We then use the
charAt() method to get the character at index
7 in the string. The
charAt() method takes a single argument, which is the index of the character to return. In this case, we pass in the number
7 as the argument.
As a result of calling the
charAt() method, the
result variable will be set to
'w', which is the character at index
7 in the
string1 string. If the index we were searching for was out of range (i.e., if we passed in a number greater than the length of the string), the
result variable would be set to an empty string.
