overl8d

Overload your function easi-fastest way

Installion

npm install overl8d

Idea

overl8d(
  String,/*Type, Type, Type, ...*/
  function (str) {} /* unnamed callback function */
)

Idea of overl8d is simple. Put overl8d function's parameters object types how many do you want, and put unnamed callback function in it (it really must be unnamed), overl8d makes calculations for you and generates new function. if you want to overload 0 (zero) parameter, just do not put any type... look down pls.

overl8d(
  function () { console.log("hi");}
)(); // writes hi in console

You can use own types. But make sure you put name of them!

function MyClass() {
  this.hello = function() {
    console.log("hello");
    return 0;
  }
}

var myClass = new MyClass();
overl8d(MyClass, function(myClass) {
  myClass.hello() 
})(myClass); // writes "hello" returns 0

Using in nodejs

var overl8d = require("overl8d");

/** @construct */
function Size(x, y) {
  this.x = x;
  this.y = y;
}

var Add = overl8d(Size, Size, function (size, size2) {
  return new Size(size.x + size2.x, size.y + size2.y);
},
Number, Number, Number, Number, function(x, y, x2, y2) {
  return new Size(x + x2, y + y2);
});

var size = new Size(1, 3);
var size2 = new Size(4, 5);
Add(size, size2); // Size {x: 5, y: 8}
Add(1, 3, 4, 5); // Size {x: 5, y: 8}

using it on browser without amd

<!-- load from nodemodules folder -->
<script src="../node_modules/overl8d/overl8d.js"></script>

after load

var Add = overl8d(String, Function, function(s, f) {});

using it on browser with amd

require(['../node_modules/overl8d/overl8d.js'], function(overl8d) {
  var Add = overl8d(String, Function, function(s, f) {});
});
