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.
Syntax
toLocaleString()
toLocaleString(locales)
toLocaleString(locales, options)
Parameters
locales- : A string with a BCP 47 language tag, or an array of such strings. For the general form and interpretation of the
localesargument, see the parameter description on theIntlmain page.
- : A string with a BCP 47 language tag, or an array of such strings. For the general form and interpretation of the
options- : An object with configuration properties. See Number.prototype.toLocaleString.
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"
