Basic JavaScript (31/111) | Use Bracket Notation to Find the First Character in String |freeCodeCamp

Bracket notation is a way to get a character at a specific index within a string.

Most modern programming languages, like JavaScript, don't start counting at 1 like humans do. They start at 0. This is referred to as Zero-based indexing.

For example, the character at index 0 in the word "Charles" is "C". So if var firstName = "Charles", you can get the value of the first letter of the string by using firstName[0].

Example:
var firstName = "Charles";
var firstLetter = firstName[0]; // firstLetter is "C"
