Definition and Usage

The toLocaleUpperCase() method converts a string to uppercase letters, according to the host's current locale.

The locale is based on the language settings of the browser.

Generally, this method returns the same result as the toUpperCase() method. However, for some locales, where language conflict with the regular Unicode case mappings occurs (such as Turkish), the results may vary.

Note: The toLocaleUpperCase() method does not change the original string.

Tip: Use the toLocaleLowerCase() method to convert a string to uppercase letters, according to the host's current locale.
