JavaScript String codePointAt() Method

Get code point value at the first position in a string:

let text = "HELLO WORLD";
let code = text.codePointAt(0);

Get the code point value at the second position:

let text = "HELLO WORLD";
let code = text.codePointAt(1);

More examples below.

The codePointAt() method returns the Unicode value at an index (position) in a string.

The index of the first position is 0, the second is 1, ....

charCodeAt() is UTF-16, codePointAt() is Unicode.

charCodeAt() returns a number between 0 and 65535.

Both methods return an integer representing the UTF-16 code of a character, but only codePointAt() can return the full value of a Unicode value greather 0xFFFF (65535).

For more information about Unicode Character Sets, visit our Unicode Reference.

string.codePointAt(index)

Get the code point value at the last position:

let text = "HELLO WORLD";
let code = text.charCodeAt(text.length-1);

let text = "HELLO WORLD";
let code = text.charCodeAt(15);
