Can you tell me the name of the Javascript "protocol" or "custom" being referred to here?

From what I can gather, the requests array seems to consist of functions with unique formatting and syntax. However, I'm struggling to find relevant search terms to help me better understand it:

var requests =  {
  rewardPoints: function(cb) {
    io.getRewardPoints(require.mozuData('user').accountId).then(function(rewards) {
      add('rewardPoints', rewards);
      cb();
    }, function() {
      add('rewardPoints', null);
      cb();
    });
  },
  segment: function(cb) {
    io.getMySegment().then(function(res) {
      add('segment', res);
      cb();
    }, cb);
  }, ...................

The code snippet continues with additional names followed by a colon in a similar manner. Is this perhaps an array where each variable serves as a function? Can I invoke these functions using their names as I would with any other function? For example:

rewardPoints();    
segment();

Is there a specific term or practice associated with this convention?

javascript

Answer №1

It's simply known as object literal notation, and it represents an object rather than an array.

Am I able to invoke these functions by their names like any other function?

Absolutely.

rewardPoints();

No, you can't. They are methods of an object, not standalone variables.

requests.rewardPoints();

Answer №2

This code snippet showcases a unique use case for Javascript objects by incorporating functions as values instead of regular data.

var requests = {
  rewardPoints: <.. function() ..>, 
  segment: <.. function() ..>
}

By assigning functions as values, you can dynamically execute them by simply referencing the keys and adding parentheses.

To call the functions, follow these examples:

requests.rewardPoints // < -- access the function
requests.rewardPoints() // < -- invoke the function
