Avoid `eval()` Due to Significant Security Risks

JavaScript Analyzer

What is this warning?

Your code is using the `eval()` function. This is extremely dangerous. The `eval()` function executes any string as JavaScript code, which can open your website up to major security vulnerabilities, particularly Cross-Site Scripting (XSS) attacks. There is almost always a safer, better alternative.

How to Fix This Issue

How to Fix It

The Problem

eval('alert("Hello World")');

The Solution

Refactor your code to avoid executing strings. If you need to parse JSON, use `JSON.parse()`. If you need to call a function by name, access it as a property of the `window` object.

Why This Works

Removing `eval()` closes a significant security hole. The mantra in the JavaScript community is "eval is evil" for a good reason. Always look for a safer way to achieve your goal.
