Syntax

String.fromCharCode(number1)

String.fromCharCode(number1, number2)

String.fromCharCode(number1, number2, ..., numberN)

Parametersnumber1, ..., numberN - sequence of integer numbers that are UTF-16 code units (in a range between 0 and 65535 (0xFFFF))
ResultThis method returns a string of length N (not a String object), consisting of the N specified UTF-16 code units.
DescriptionThe CharCode() is a static method that returns a string created from the specified sequence of UTF-16 code units.

2. Practical example

In this example, we use the fromCharCode() method to return strings consisting of the specified UTF-16 code units.

// ONLINE-RUNNER:browser;

console.log(String.fromCharCode(97, 98, 99)); // abc

console.log(String.fromCharCode(960)); // π
console.log(String.fromCharCode(945)); // α
console.log(String.fromCharCode(946)); // β

Output:

abc
π
α
β
