Pretend I'm a tech novice. Can you explain what Namespacing in JavaScript is in plain English?

This is a fundamental JavaScript question that should be easy for its experienced web developers to answer. The key here is using plain English as though you were speaking with somebody who had no technical background. This requires you not to use acronyms or any jargon somebody from outside the industry would not understand.

"When programming in JavaScript, which is a common language used by web developers, namespace is known as a global object. This is an element within the webpage. Its purpose is to identify specific properties and objects displayed on the webpage. It helps developers to reuse some of the code they've already developed and also prevents conflicts from occurring within the webpage."
