SOM-JavaScript

Utilities for JavaScript, part of SOM utilities.

iterate

Iterates asynchronously over a collection, performing each iteration only once the previous one finished.

Example of printing out 1, 2 and 3 to console asynchronously and in the series:

var som = require('som.js');

som.iterate([1, undefined, 3], function(nextIteration, item, isFinished) {
  //  isFinished will be true only once all the items in the collection have
  //  been iterated over.
  if(!isFinished) {
    console.log(item);
  }

  //  To continue with iteration invoke the provided nextIteration() function.
  //  To stop the iteration don't do anything.
  //  Invoking nextIteration() on finished iterations is neither required nor
  //  prohibited as it doesn't do anything.
  nextIteration();
});

The above should output:

1
undefined
3

iterateSync

Same as iterate but performs the iteration synchronously before continuing.
