how to access a defined variable from another variable where the content is the name of the defined variable (java script)

Question

var q2312="{'hello world'}";var autogenname="q2312";

I auto generate a variable called "autogenname" from razor pages where the content refers to the defined variable. e.g. "q2312" refers to the defined variable name q2312. How do i access the var q2312?

You can access global variables (defined with var) via window

var q2312="{'hello world'}";
const autogenname="q2312";

console.log(window[autogenname])

I don't know your exact use case, but in general I wouldn't recommend doing it over the global space. Instead you could store the variables in an object and then access it via the keys:

const myData = {
 q2312: 'Hello World'
}

const autoGenName="q2312";

console.log(myData[autoGenName])
