what is javascript-fu?

javascript-fu is a martial arts discipline (library) for node.js and the browser. through mastering the art of javascript-fu you will be a nimble, yet powerful JavaScript developer. a true javascript-fu master can avoid the bad parts of javascript with ninja-like agility and perform quick and devastating blows to produce robust, succinct code that covers a myriad of common functionalities.

where did javascript-fu come from?

javascript-fu is the culmination of years of training in the archaic art of javascript. through meticulously studying the following ancient scrolls we have divined the ultimate form of javascript martial arts.

Underscore.js, jQuery.js, date.js, Rails Inflectors, Coldfusion's DateFormat and TimeFormat, Microsoft's LINQ

how do i use javascript-fu?

if you don't like reading documentation, check out the interactive javascript-fu demo

browser

  <script src = "js-fu.js" type = "text/javascript"></script>
  <script>
    var x = fu.isNumber(13); // true
    var x = fu.isDate('07/01/2010'); // true
  </script>

node.js

  var fu = require('./js-fu');
  var x = fu.isNumber(13); // true
  var x = fu.isDate('07/01/2010'); // true

once you have required the js-fu library, you have access to the "fu" object. inside this object you will find ...

  • isArray
  • isBoolean
  • isDate
  • isDefined
  • isEmpty
  • isEqual
  • isFunction
  • isJSON
  • isNode
  • isNull
  • isNumber
  • isObject
  • isRegExp
  • isString
  • isText

toFu - the deadly art of the monkey punch

toFu methods will accept anything as an argument and aggressively attempt to coerce the value into the type you have specified

  • toCamel
  • toChain
  • toDash
  • toHuman
  • toJSON
  • toLink
  • toMix
  • toNumber
  • toOrdinal

  • getIndex
  • getKeys
  • getLast
  • getLeft
  • getLinks
  • getNode
  • getRandom
  • getRight
  • getValues

dateTimeFu - the art of space and time

Try out the interactive demo of Date.format()

dateTimeFu adds a new method "format" to the built in JavaScript Date object

Date.format() takes one argument, a formatting mask
you can use a pre-defined formatting mask or an inline mask. you can also define new re-usable masks

      var now = new Date();
      now.format("shortDate"); // ouputs: 7/1/10
      now.format("mm/dd/yyyy"); // outputs: 07/01/2010

pre-defined dateTime masks

Name Mask Example
default ddd mmm dd yyyy HH:MM:ss Sat Jun 09 2010 17:46:21
shortDate m/d/yy 6/9/07
mediumDate mmm d, yyyy Jun 9, 2010
longDate mmmm d, yyyy June 9, 2010
fullDate dddd, mmmm d, yyyy Saturday, June 9, 2010
shortTime h:MM TT 5:46 PM
mediumTime h:MM:ss TT 5:46:21 PM
longTime h:MM:ss TT Z 5:46:21 PM EST
isoDate yyyy-mm-dd 2010-06-09
isoTime HH:MM:ss 17:46:21
isoDateTime yyyy-mm-dd'T'HH:MM:ss 2010-06-09T17:46:21
isoUtcDateTime UTC:yyyy-mm-dd'T'HH:MM:ss'Z' 2010-06-09T22:46:21Z

linqFu - the forbidden art of querying JSON with LINQ, liberated from...Microsoft

Try out the interactive demo of JSLINQ
linqFu is adds the JSLINQ project which is a pure javascript implementation of gasp Microsoft's LINQ query language. it's very usefull for quickly querying JSON objects.

simple Select

var sample = fu.linq(sampleData).
  Select(function (item) {return item.FirstName;});
output: {"items":["Chris","Kate","Josh","John","Steve","Katie","Dirk","Chris","Bernard","Kate"]}

simple Select with OrderBy

     var sample = fu.linq(sampleData).
      Select(function (item) {return item.FirstName;}).
      OrderBy(function (item) {return item;});
     output: {"items":["Bernard","Chris","Chris","Dirk","John","Josh","Kate","Kate","Katie","Steve"]}

simple Where

  var sample = fu.linq(sampleData).Where(function (item) {return item.FirstName == "Chris";});
  output: [
             {"ID":1,"FirstName":"Chris","LastName":"Pearson","BookIDs":[1001,1002,1003]},
             {"ID":8,"FirstName":"Chris","LastName":"Stevenson","BookIDs":[4001,4002,4003]}
            ]
