the.types v1.0.3

the.types

the.types has Set, Map, Array data structures.

What is the goal of this project?

This project allows you to have Map, Set and Array data structures with many functionalities. I had created these types for a project then I started to use them in many projects.

Installation

$ npm install --save the.types

Usage

var theTypes = require('the.types');


// Map usage

var obj = {
  firstname: 'test_firstname',
  lastname: 'test_lastname'
};

var emptyMap = theTypes.map();
var theMap = theTypes.map(obj);

console.log(theMap.get('firstname'));
console.log(theMap.get('lastname'));

var valuesOfMap = theMap.values();
console.log(valuesOfMap.get(0)); // first value

var keysOfMap = theMap.keys();
console.log(keysOfMap.get(0)); // first key

var map = types.map();
map.put('key1', 'test1');
map.put('key2', 'test2');
theMap.putAll(map);

var map = types.map();
map.put('key1', 'test1');
map.put('key2', 'test2');
map.put('key3', 'test3');
console.log(map.join(":", ",")); //key1:test1,key2:test2,key3:test3

// Set usage

var set = theTypes.set();
set.put("test_1");
set.put("test_1");
set.put("test_2");
console.log(set.size()); // prints 2

var values = set.values();
values.get(0); // returns test_1
values.get(1); // returns test_2

set.frequencyOf("test_1"); // returns 2

// Array usage

var array = theTypes.array();
array.add("test1");
array.add("test2");
array.get(1); // returns test2
array.length(); // returns 2


var array = types.array();
array.add("test_1");
array.add("test_2");
array.add("test_3");
array.add("test_4");

var result = array.filter(function(index, item){
  var no = item.split("_")[1];
  return no%2==0;
});

result.length(); // returns 2


array.frequencies().frequencyOf("test_1"); // returns 1


var array = theType.array();
array.add("test_1");
array.add("stopper");
array.add("test_4");
var resultArray = new types.array();

array.iterate(function(index, item)
  {
    if(item === "stopper")
    {
      return false;
    }

    resultArray.add(item);
});

resultArray.length(); // returns 1
resultArray.get(0); // returns test_1


var intersections = array_1.intersections(array_2);
array_1.contains("test_3");
array_1.containsAny(array_2);
array_1.containsAll(array_2);

Test

This module is well tested. You can run:

• npm test to run the tests under Node.js.
