ReactJS how to refer to an object using another variable

Question

I have a variable containing a string. This string is itself the name of another object.

say

const myObject = {"some": "Object in JSON format"};

const myObjectName = 'myObject';

How can I use the string contained in the variable 'myObjectName' to call a function manipulating myObject?

You can't touch a variable name using a string as far as I know — kyun

Seriously? It's possible the function doesn't exist but doesn't that make the language non Turing complete? — Huw Evans

const myObject = {"some": "Object in JSON format"};
const myObjectName = 'myObject';
function myFunction (obj) {
   console.log(obj);
}

eval(`myFunction(${myObjectName})`);

This works but eval is dangerous and should be avoided
