how can i make a function return the contents of an array? ex. function print(array)

i want to write a function called print that will return the variables in an array to the console. i have this so far:

function print(array, instructions) { var output = []; for (var i=0; i<array.length;i++) { output.push(instructions(array[i])); } return output; }

.....im not sure what to do.

Can you use an example to explain what exactly do you want to achieve? For example you want to convert a var array = [0,1,2,3] into what?

function print() {
            for (var i = 0; i < arguments.length; i++) {
                console.log(arguments[i])
            };
        }
//Example
        print("12",23,"Hola",12,44)

Here is a quick fix for your code:

var arrayToConvert = ["12",23,"Hola",12,44];

function print(parameter) {
            for (var i = 0; i < parameter.length; i++) {
                console.log(parameter[i])
            };
        }

print(arrayToConvert);
