1. Each team has to come here to the stage, and the team members have to pick up 5 chits (in total).
   This will be done for each and every team.
   These 5 words are crucial for you.
   Each team has to make some sense out of any 3 word combinations of the 5 words and build something by keeping in mind those 3 words.

For example, if someone got

Health, News, Alcohol, Fake, Meme
Then they have to choose any of the 3 word combinations and make sense out of them, like Health-News-Alcohol, Fake-Health-Meme......

app.use(express.static(path.join(__dirname, 'b')));

Right, app.use() loads a function to be used as middleware. In this context, it loads the result of express.static(path.join(__dirname, 'public')).

The result of express.static(path.join(__dirname, 'public')) is a function (in JavaScript, functions may return functions), a function that express understands as a middleware (i.e. it has the following signature: function(request, response, next) {

express.static() is a function that takes a path, and returns a middleware that serves all files in that path to /. (If you wanted to prefix it with /public or whatever, you'd write app.use('/public', express.static(path.join(__dirname, 'public'))), where the first /public is the web path and the second is the filesystem path of the files being served).

For better clarity, the following:

Understanding callback functions in Javascript


Callback functions are extremely important in Javascript. They’re pretty much everywhere.

If you’re coming from a background in functional programming, or you have experience in writing concurrent programs in other languages, you might not have any difficulty understanding why callback functions are used the way they are in Javascript programs, but I’ve talked to more than one programmer who found the concept very unintuitive.

Functions are objects

To understand callback functions you first have to understand regular functions. This might seen like a “duh” thing to say, but functions in Javascript are a bit different than (for example) methods in Java. Functions in Javascript are first-class, and are actually objects.

                The significance of this.props.children
              
          
    Some components don't know their children ahead of time. This is especially common for components like Sidebar or Dialog that represent generic "boxes".
We recommend that such components use the special children prop to pass children elements directly into their output:
function FancyBorder(props) {
  return (
    <div className={'FancyBorder FancyBorder-' + props.color}>
      {props.children}
    </div>

);
