Questions tagged [javascript-namespaces]

JavaScript namespaces provide a level of direction to specific identifiers, thus making it possible to distinguish between identifiers with the same exact name.

In order to reduce the number of objects and functions that are added to the global scope in our applications, using namespaces in JavaScript is definitely a recommended practice. Just like static members, namespaces don’t have any dedicated syntax built into the language either. But we’re able to get the same benefits by creating a single global object and adding all our objects and functions to this object. This way we lower the possibility of naming collisions when using our code in conjunction with other JavaScript libraries. We can also use the same naming conventions for namespaces as in any other programming language that does provide syntactical support.
