String toLocaleLowerCase() method

Find all information about the JavaScript toLocaleLowerCase() method of the string

According to the case mapping of the locale, it returns a new string converted from lowercase letters of the original string.

The first parameter represents the locale, but it is optional (if omitted, the current locale is used):

'Testing'.toLocaleLowerCase() //'testing'
'Testing'.toLocaleLowerCase('it') //'testing'
'Testing'.toLocaleLowerCase('tr') //'testing'

As usual, internationalization may not bring benefits, but I read on MDN that Turkish first does not have the same case mapping in other languages.

Similar totoLowerCase()Method, except that the language environment is not considered.
