This article has been given a more permanent home on my blog. Also, since it was first written, the development of the Promises/A+ specification has made the original emphasis on Promises/A seem somewhat outdated.

You're Missing the Point of Promises

Promises are a software abstraction that makes working with asynchronous operations much more pleasant. In the most basic definition, your code will move from continuation-passing style:

getTweetsFor("domenic", function (err, results) {
 // the rest of your code goes here.

# Five lines of code that will make your underscore + CoffeeScript use cleaner.
# Creates an underscore function for each function in to_reverse with R (short for Reversed) appended to the name.
# The R version moves the function argument (first argument in normal underscore) to the end, 
# so you can write:
$(window).scroll _.throttleR 500, ->
    console.log "This print's at most every 500ms"

# Instead of:
$(window).scroll _.throttle ->
        console.log "This prints at most every 500ms too"

This is a fork of Bootstrap Typeahead that adds minimal but powerful extensions.

For example, process typeahead list asynchronously and return objects

  # This example does an AJAX lookup and is in CoffeeScript
  $('.typeahead').typeahead(
    # source can be a function
    source: (typeahead, query) ->
 # this function receives the typeahead object and the query string

• New applications get a flag config.active_record.auto_explain_threshold_in_seconds in the environments configuration files. With a value of 0.5 in development.rb, and commented out in production.rb. No mention in test.rb. fxn

Debug mode for running .coffee scripts #558, #987

Adds a --debug option for .coffee scripts that outputs more helpful error messages (mapping compiled .js lines of code to the input .coffee file's lines).

This branch should be considered experimental at the moment -- it serves as a proof-of-concept and to expose additional issues with adding debugging support to CoffeeScript

Current output:

TypeError: string is not a function
