What is safe-array-iterator?

In JavaScript, arrays come with a built-in way to loop through their items one by one, a process called iteration. However, JavaScript is a language where the fundamental building blocks of arrays can be modified by other code running in the same program. If another piece of code accidentally or intentionally changes how arrays are supposed to iterate, your code might suddenly break or behave unpredictably. This project provides a tool to loop through arrays safely, protecting your code from that kind of interference. The way it works is straightforward. Instead of relying on the array's own potentially tampered-with looping mechanism, this tool provides a reliable wrapper. You pass your array into it, and it hands back a safe, dependable way to step through each item. Even if someone has altered the default behavior of arrays in your environment, this wrapper ensures you can still iterate through your items exactly as you expect, from the first element to the last. This tool is primarily for JavaScript developers building applications, libraries, or tools that need to run in shared or unpredictable environments. For example, if you are writing a utility library that other developers will install into their own projects, you cannot always control what other code is running alongside yours. If another library modifies core array behaviors, it could break your library. By using this safe iteration method, you ensure your code remains stable and secure regardless of what else is happening in the host application. The project is a very small, focused utility. It does not attempt to solve broader problems beyond safe array iteration, which means it is lightweight and does exactly what it promises. The README does not go into further detail on its internal implementation, but the core concept is simply to provide a defensive programming tool for a specific edge case in the JavaScript language.
