Let’s go through an example of different ways to call a function in JavaScript. Let’s say we have a function that prints Hello World to the console. We can call this as:
function HelloWorld() {
console.log("Hello World");
}
HelloWorld();
This function can also be assigned an anonymous variable and called as below:
var i = function() {
console.log("Hello World");
}
i();
Or also run immediately as:
var i = function() {
console.log("Hello World");
}();
