How to get variable outside export function

Question

How can I call const variable in same file but outside export const

 export const getData = async ({page="1",limit="10", createdAt="}) => {

    }

I want to crate variable like this

const params = {
  page = "1",
  limit = "10",
  createdAt="",
}

and In export I want to call some thing like this

 export const getData = async (params) => {

   }

the reason that I want to do like this because I want to make my code more easy to read thanks

Answer 1

By using a self invoking function that return a closure:

const getData = ((params) => {
    return async () =>{
        console.log(params)
    }
})({foo:'bar'})
