TypedArray.prototype.toLocaleString()

The toLocaleString() method of TypedArray instances returns a string representing the elements of the typed array. The elements are converted to strings using their toLocaleString methods and these strings are separated by a locale-specific string (such as a comma ","). This method has the same algorithm as Array.prototype.toLocaleString().

Try it

Syntax

toLocaleString()
toLocaleString(locales)
toLocaleString(locales, options)

Parameters

Return value

A string representing the elements of the typed array.

Description

See Array.prototype.toLocaleString() for more details. This method is not generic and can only be called on typed array instances.

Examples

Using toLocaleString()

const uint = new Uint32Array([2000, 500, 8123, 12, 4212]);

uint.toLocaleString();
// if run in a de-DE locale
// "2.000,500,8.123,12,4.212"

uint.toLocaleString("en-US");
// "2,000,500,8,123,12,4,212"

uint.toLocaleString("ja-JP", { style: "currency", currency: "JPY" });
// "￥2,000,￥500,￥8,123,￥12,￥4,212"
