charAt | Itential

The charAt task returns a character at a given index. The index of the first character in the string is 0, the second character is 1, and so on. When the index value is specified, the return result will be the character at that index location in the string.

Potential use case

Suppose you have a long list of numbers and you want to verify that a certain number is located at a certain position in the index. You could use the charAt task for that validation.
