The minimum required to use Webpack is the following command: webpack ./src/index.js ./dist/bundle.js // this is equivalent to: webpack source-file destination-file Web pack will take the source file, compile to the output destination and resolve any dependencies in the source files.

Active patterns are just simple functions. Like functions you can define additional parameters: let (|HasExtension|_|) expected (uri : string) = let result = uri.EndsWith (expected, StringComparison.CurrentCultureIgnoreCase) match result with | true -> Some true | _ -> N...

The plotly package allows many kind of interactive plots, including maps. There are a few ways to create a map in plotly. Either supply the map data yourself (via plot_ly() or ggplotly()), use plotly's "native" mapping capabilities (via plot_geo() or plot_mapbox()), or even a combination o...

A do-while loop is very similar to a while loop, except that the condition is checked at the end of each cycle, not at the start. The loop is therefore guaranteed to execute at least once. The following code will print 0, as the condition will evaluate to false at the end of the first iteration: i...
