Calling function defined in an IIFE function from HTML

Question

I have a IIFE function in a file called test.js i.e.

(function mainIIFE() {
    \"use strict\";
    var print_name = function(first, last) {
        console.log(         


        

Answer 1

You can return the function and store it in a variable. This is essentially the same as assigning it to window.print_name inside the IIFE since the new variable will be in global namespce

var print_name = (function mainIIFE() {
    "use strict";
    var print_name = function(first, last) {
        console.log(first + " " + last);
    };
    return print_name;
}());

print_name('Foo','Bar')

Answer 2

Since you declare print_name with var, its scope is local to the IIFE, so you can't call it from outside there. You need to assign to window.print_name to make it global.

(function mainIIFE() {
    "use strict";
    window.print_name = function(first, last) {
        console.log(first + " " + last);
    };
}());

It's also not clear why you're using new to call the function, since it doesn't fill in an object.
