Named Optional Parameters - JavaScript Style Brian Davidson (briandavidson@meta.com) Summary C++ developers often run into the situation where we have multiple parameters in a function with the same send(source=from) send(destination=to) send(destination=from) # valid python - can C++ do better? Optional named arguments are previously thought to not be possible in C++. Is it possible to write such

Prerequisites: Tornado 6.2 requires Python 3.7 or newer. The following optional packages may be useful: pycurl [http://pycurl.io/] is used by the optional tornado.curl_httpclient. Libcurl version 7.22 or higher is many keyword arguments that can be used to customize the behavior of the application and enable optional features; see Application.settings for the complete list. Subclassing RequestHandler Most of the use self.redirect() within a RequestHandler method to redirect users elsewhere. There is also an optional parameter permanent which you can use to indicate that the redirection is considered permanent.

for, while, and do-while to make loops. Parentheses around the condition or loop variable are optional. Braces around the body are required. 1 let individualScores = [75, 43, 103, 87, 12] 2 var teamScore optionals. An optional value either contains a value or contains nil to indicate that the value is missing. Write a question mark (?) after the type of a value to mark the value as optional. 1 var optionalString: different greeting if optionalName is nil. If the optional value is nil, the conditional is false and the code in braces is skipped. Otherwise, the optional value is unwrapped and assigned to the constant
