The String charCodeAt() method
By Flavio Copes
Learn how the JavaScript charCodeAt() method returns the Unicode 16-bit integer code for the character at a given index in a string, unlike charAt().
~~~
Return the character code at the index i. Similar to charAt(), except it returns the Unicode 16-bit integer representing the character:
'Flavio'.charCodeAt(0) //70
'Flavio'.charCodeAt(1) //108
'Flavio'.charCodeAt(2) //97Calling toString() after that will return the hexadecimal number, which you can lookup in Unicode tables like this.
