What is the process for extracting values from a Proxy object and assigning them to a local variable?

Can anyone help guide me on how to retrieve a list of devices (video and input/output audio) using navigator.mediaDevices.enumerateDevices()? I created a function that returns the result, but when I try to display it with console.log(result), I only see a proxy object. How can I extract this result and assign it to a local variable?

Proxies can be generated by Vue or through asynchronous tasks. In your specific situation, there is no need for any additional actions as your array functions just like a regular array. You can easily assign the result value to any variable of your choice, and it will work perfectly.
