Scope And Namespace Questions

I was examining various JavaScript libraries for learning purposes. Basically I want to find the best way to initiliaze a namespace and see how pros load up all the associated file

Solution 1:

JS does not assign "by reference", assignment is copying, but when we assign objects, we copy their addresses, not objects "themselves".

Look

window.MyNameSpace = ["libraryFile1.js", "libraryFile2.js", "libraryFile3.js"]

window.MyNameSpace point to some object in memory. Let's assume its address is 0x12345

var jsFiles = window.MyNameSpace;

jsFiles now points to the same object (0x12345)

window.MyNameSpace = {...}

window.MyNameSpace now points to some other object (let it be 0x56789), but jsFiles still points to the first object (0x12345).
