What is the difficulty level of this exercise?
Unlike other languages, JavaScript doesn’t have equivalent for function strftime. Javascript however provides multiple functions to present date and time in human readable form. They are:
toDateString Converts the date portion of a Date object into a readable string toGMTString Deprecated. Use the toUTCString() method instead toISOString Returns the date as a string, using the ISO standard toJSON Returns the date as a string, formatted as a JSON date toLocaleDateString Returns the date portion of a Date object as a string, using locale conventions toLocaleTimeString Returns the time portion of a Date object as a string, using locale conventions toLocaleString Converts a Date object to a string, using locale conventions toString Converts a Date object to a string toTimeString Converts the time portion of a Date object to a string toUTCString() Converts a Date object to a string, according to universal time
