Choosing a random value from an array and then saving that value to do other things to.

Ok I'm stuck and I think the awnser is stupidly basic

I have an array of proxies var proxies = [proxy1, proxy2, proxy3, proxy4,proxy5]

I then choose a random proxy using

var proxytouse = await proxies[Math.floor(Math.random() * proxies.length)];

Which chooses a random proxy to use in my script. Problem is I need to save the proxy that proxytouse chooses so that if it hits a captcha I can then remove it from my array and save that proxy to a database of proxies which needs checking.

it sounds simple but every time I call proxytouse it will always choose a random proxy

The use of "await" is rather mysterious in this snippet, but for altering the array, you probably want to know the index value rather than the chosen value. So it makes sense to choose in 2 steps, and then the index can be directly used later:

var lastproxyindex = Math.floor(Math.random() * proxies.length);
var proxytouse = proxies[lastproxyindex];

For a more complete analysis and specific answer, show more of the code (particularly the promise and async function).
