JavaScript String toLocaleLowerCase() Method

JavaScript String toLocaleLowerCase() method is used to convert a string to lowercase letters, using the current locale. The locale is based on the language settings of the browser. This method does not modify the original string.

Syntax

string.toLocaleLowerCase(locale)

Parameters

locale(optional): It is the parameter that indicates locale to convert to the lowercase according to any locale-specific case mappings. If multiple locales are given in the Array, the best available locale is used.

Return value

Returns the string representing the value of a string converted to lowercase according to the host’s current locale.

appdividend

Example 2: Using different localesVisual Representation of Using different locales

let text = 'AppDividend'; 
console.log('EN-US: ' + text.toLocaleLowerCase('en-US')); 
console.log('TR: ' + text.toLocaleLowerCase('tr'));
console.log('De: ' + text.toLocaleLowerCase('de-DE'));

Output

EN-US: appdividend
TR: appdividend
De: appdividend

In the above example, we applied the toLocaleLowerCase()  method to the string ‘AppDividend‘ using various locale settings: U.S. English (en-US), Turkish (tr), and German (de-DE). The output is ‘appdividend‘ for all specified locales because ‘AppDividend‘ does not contain any locale-specific characters that the locale parameter in the method would affect.
