Difference between str[0] and str.charAt(0)
javascript, string
Solution
`[]` is a more primitive way of accessing all kind of arrays.
`charAt()` is specific to strings.
You can access the index of any array by using `[]`, but you can only use `charAt()` on a string.
But when it comes to string alone, both are one and the same.
But you should use `charAt()` because, it is well supported in all the major browsers, while the bracket notation will return `undefined` in IE7
Also, the bracket notation is simply accessed, while `charAt()` does some validation and doesn't return `undefined`, but will return an empty string `""`
Problem
What is the difference between `str[0]` and `str.charAt(0)`? I always access specific character by simply typing `str[i]`, where `i` is the index of the character I want to access (counted from 0), but last week I had good overview of open source JS code, and in every single project I saw, people use `charAt` method. Is there any difference between those two ways?
