Namespaces in JavaScript

Introduction

To group functions and to avoid overwriting functions by defining them more than once one can use namespaces. JavaScript does not have namespaces, but a similar effect can be achieved by defining objects with functions, as shown below.

source(findFile("scripts", "misc.js"))

function main() {
    test.log("" + misc.add(1, 1));
    test.log("" + misc.subtract(1, 1));
}
test.js
misc = {
    add: function(a, b) {
        return a + b;
    },

    subtract: function(a, b) {
        return a - b;
    }
}
misc.js

Alternative syntax:

misc = {};

misc.add = function(a, b) {
    return a + b;
};

misc.subtract = function(a, b) {
    return a - b;
};
misc.js
