The answer is has a simple answer, but it doesn't to be simplified by the answers in this thread. The simple answer is yes you can place function in an array. In fact, can declare variables and reference them in your function.

Example:

let a = 1;
let b = 2;

let arr = [
  a,
  b,
  function () {
    return a + b;
   },
  ];

console.log(arr[2]()); // return 3
console.log(typeof arr); // returns object
