use two same name method in different .js files

Question

I have two methods with the same name, for different purposes in 2 different .js files. How can I use those methods on same page?

In Count.js:

function add()
{
// some manipulation doing here
}

In PriceImplement.js

Function add()
{
// some manipulation doing here
}

Answer 1

If they're both defined using function declarations, like

function iHaveTheSameNameAsAnotherFunction(params) {
    …
}

then you can't. The second declaration will simply overwrite the first one.

Answer 2

You should get into the habit of namespacing your JavaScript-files:

//Count.js:

var Count = {
  add: function add() {
  },
  [additional methods in the Count object]
};

// PriceImpl.js

var Price = {
  add: function add () {
  },
  [additional methods for the Price implementation]
};

Then call methods like Namespace.method, i.e. Price.add()
