String.charCodeAt() method is used to get the Unicode-16 character from the string at given index.
stris a string.
nis an integer (position/index).
charCodeAt() method returns the UTF-16 code (unicode) character (as integer) from string
str present at the index
1. In the following program, we get unicode character in the string
name at index=3.
let name = 'apple'; let output = name.charCodeAt(3); console.log(output);
2. In the following program, we take the index
n such that the it outside the range of string, then
charCodeAt() must return
NaN (Not a Number).
let name = 'apple'; let output = name.charCodeAt(15); console.log(output);
