The String charCodeAt() method

Just a few weeks until the 2021 JavaScript Full-Stack Bootcamp opens.
Signup to the waiting list!

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) //97

Calling toString() after that will return the hexadecimal number, which you can lookup in Unicode tables like this.

The 2021 JavaScript Full-Stack Bootcamp will start at the end of March 2021. Don't miss this opportunity, signup to the waiting list!
