How to create a function in javascriptJavascript By TechWhizKid on Apr 5 2020
function addfunc(a, b) {
  return a + b;
  // standard long function
}

addfunc = (a, b) => { return a + b; }
// cleaner faster way creating functions!

function idk() {
	alert('This is an alert!')
}
//call the function to make the function run by saying "Name of function + ()"
idk()

A function is a reusable block of code that allows you to 
input specific values. To specify the values you need to call
the function by typing the name along with the desired values
spaced by commas.

function myFunction(value1, value2) {
	return value1 + value2;
}

myFunction(10, 5);




Now the function will return 15.

function sayHelloTo(to) {
  alert(`Hello ${to}`);
}
sayHelloTo('World from Grepper')

function myFunction() {
  alert("ALERT!");
}

myFunction();

function myFunction(p1, p2) {
    return p1 * p2;  
//  The function returns the product of p1 and p2
}

or

var myFunction = function(p1, p2) {
	return p1 * p2;  
//  The function returns the product of p1 and p2
};
