Answer 1

An array can be passed to a module by including it as one of the parameters of the module's function. When the function is called, the array can be passed as an argument to that parameter.

A parameter is a placeholder in the function's definition that represents a value that will be passed to the function. An argument, on the other hand, is the actual value that is passed to the function when it is called.

For example, let's say we have a module that is supposed to calculate the sum of all the elements in an array. The module's function might look something like this:

```
function sumArray(arr) {
let sum = 0;
for (let i = 0; i < arr.length; i++) {
sum += arr[i];
}
return sum;
}
```

In this function, `arr` is the parameter that represents the array that will be passed to the function. When the function is called, we would pass an array as an argument to this parameter, like so:

```
let nums = [1, 2, 3, 4, 5];
let arrSum = sumArray(nums);
console.log(arrSum); // Output: 15
```

In this example, `nums` is the array that we want to calculate the sum of, and `arrSum` is the variable that will hold the result of calling the `sumArray` function with `nums` as its argument.

Overall, the process of passing an array to a module involves defining a parameter in the module's function that represents the array, and then passing the actual array as an argument when the function is called.
