tempdate.tolocaledatestring(preferredculture, month) how to get month from the capital letter for the french culture in javascript

To get the month from the capital letter for the French culture in JavaScript, you can use the toLocaleDateString() method with the options parameter that accepts a localeMatcher property with the value of "best fit" or "lookup". Then, you can set the month parameter to "long", "short", or "narrow" depending on your preferred formatting.

Here's an example code snippet:

index.tsx
const preferredCulture = "fr-FR";
const options = { month: "long", localeMatcher: "lookup" };
const date = new Date();
const month = date.toLocaleDateString(preferredCulture, options);
const capitalizedMonth = month.charAt(0).toUpperCase() + month.substring(1);
console.log(capitalizedMonth); // Output: "Janvier" (for the month of January)
341 chars
7 lines

In this example, we specified the preferredCulture to be "fr-FR" for the French culture. We also set the options object with the month property set to "long" and the localeMatcher property set to "lookup". This ensures that the toLocaleDateString() method will use the most appropriate cultural settings to format the date.

After that, we created a date object representing the current date and used the toLocaleDateString() method to format the month as a string in the French culture. Finally, we capitalized the first letter of the formatted month using the charAt() and substring() methods and saved it to a capitalizedMonth variable.

The output of this code snippet is "Janvier" which is the French word for the month of January.
