javascript - How to call a function using variable in javascript without using window?

Question

Suppose there is a function (from a module) named fiveStar and I want to call it using a variable,

For e.g using window, I could do this:

const num = 'five';
const functionName = `${num}Star';
window[functionName]();

Is there any other way I could do this without using window?

You could use an object to group functions together.

const myModule = {
   fiveStar: ()=>{}
   //other methods...
};
const num = 'five';
const functionName = `${num}Star`;
myModule[functionName]();
