如何创建在 JavaScript 中生成新变量的 function？

Question

I know that there might be tons of the same question here, but being a noob I can't really understand them.

What I'd like to do is creating a function that, once we click on a button or simply activate it, it generates a new variable accesible in all the scopes, not overwriting the previous one it generated, with a different name and a value (the value can be a parameter we pass to the function or simply something taken from an array or a Math.random(), it doesn't matter). The names could be the same for all variables but followed with a _2, _3, _4 etc.

How can I do it as simple as possible?

Would you help me please? Thanks!

 var count = 1; var prefix = "prefix" function createVar(value) { var name = prefix + count; this[name] = value; ++count; } $("#button").click(function() { createVar("one value " + count); var name = prefix + (count - 1); console.log(window[name]); });

 <script src="https://ajax.googleapis.com/ajax/libs/jquery/3.5.1/jquery.min.js"></script> <button id="button">Click</button>

Now, you have access to prefix_1 on first click, prefix_2 on second click,...
