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 addfunc(a, b) {
  return a + b;
  // standard long function
}

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

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 myFunction(var1, var2) {
  return var1 * var2;
}

public void SayHello(string name) 
{
    Console.WriteLine("Hello")  
}


Console.WriteLine("What is your name?")
string name = Console.ReadLine() ; 

SayHello(Adam) 

function myFunc(param) {
  return param
}
console.log(myFunc("Hello World"))
