The string.codePointAt() is an inbuilt method in JavaScript which is used to return a non-negative integer value i.e, code point value of the specified element of the given string.
List of code point values of different elements:
Syntax:
string.codePointAt(A)
Parameters: It accepts a parameter which shows the index of an element in the string. Index starts form zero (0).
Return Values: It returns the code point value of the element which is denoted by a parameter in the string. It returns undefined if there is no element present at the specified location i.e, at “A”th index.
JavaScript code to show the working of string.codePointAt() method:
Code #1:
<script> // Taking a string "gfg" a = "gfg" // Pointing each elements of the string b = a.codePointAt(0); c = a.codePointAt(1); d = a.codePointAt(2); // Printing the code point value of each element document.write(b + "<br>") document.write(c + "<br>") document.write(d) </script> |
Output:
103 102 103
Code #2:
<script> // Taking a string "gfg" a = "gfg" // Pointing 4th index of the string // index starts from 0 b = a.codePointAt(3); // Printing the code point value document.write(b + "<br>") </script> |
Output:
undefined
Note: Output is undefined because in “gfg” there is no element at 4th index.
