Yes, a function can return an array or other data collection. In many programming languages like JavaScript and Python, this is achieved by simply declaring the array or data structure within the function and using the ‘return’ statement to output it when the function is called. For instance, in JavaScript, you could have a function that returns an array of numbers:
let numbers = [1, 2, 3, 4, 5];
In Python, a similar function might look like this:
numbers = [1, 2, 3, 4, 5]
Both functions, when invoked, will return the array
[1, 2, 3, 4, 5]
