.fromCodePoint()

The .fromCodePoint() method returns a string created using the specified sequence of Unicode code points. It allows for the creation of characters from their Unicode values, including characters beyond the Basic Multilingual Plane (code points greater than 0xFFFF).

This method is commonly used when working with emojis, special symbols, or multilingual characters in applications that require precise Unicode handling such as custom font rendering, text processing, or internationalization.

Syntax

String.fromCodePoint(num1, ..., numN)

Parameters:

• num1, ..., numN: One or more code points.

Return value:

A string formed by the given Unicode code point(s).

Note: If multiple code points are passed, the resulting string will be a concatenation of their corresponding characters.

Example

In this example, multiple Unicode code points are used to create a string containing symbols and a rare character:

console.log(String.fromCodePoint(9731, 9733, 9842, 0x2f804));

This returns a string combining the snowman (☃), star (★), recycling symbol (♲), and a rare CJK character (你).

Codebyte Example

In this codebyte example, .fromCodePoint() is used to generate both a single emoji and a string of multiple emojis:
