Introduction to RequireJS

To do modular programming you can use RequireJS. It is a JavaScript file and module loader. 

• Loads all codes relative to a baseUrl
• With paths config you can setup locations of a group of scripts
• You can define modules in RequireJS in few different ways
• Simple name/value pairs
• Definition functions
• Definition functions with dependencies
• Define module as a function
• Define a module with a name

• Only one module should be defined per JavaScript file
•  Normally you should not need to use require() to fetch a module, but instead rely on the module being passed in to the function as an argument.
• You can use global function requirejs.undef() to undefine a module
• RequireJS loads each dependency as a script tag, using head.appendChild()
