Example: js.l18

//	
	function fun_name(params) {      //parameters
   	operation.............
	}

	fun_name(params)   // call the function.
 
 
EXAMPLE:
---------
// ==================
	function func(a, b){
   console.log(`our comunity`);
   let man = 10+11;
   console.log(`${man}`)
   const arr = [ 14, 25, 31, 400, 'dulon' ];
   console.log(arr[4]);
   console.log(arr);
   console.log(`${arr}`);
   let sum = a+b;
   return sum;
   
	}
	const mn = func(5, 6);
	console.log(`sum is: ${mn}`);          
 
//=============
	function func(a, b){
   let sum = a+b;
   return sum;
}

const mn = func(5, 6);
console.log(`sum is: ${mn}`);

 
 
 
 
 
 ---------------------------------
 //  a function is simply a piece of code that we can reuse
	So it's a little bit like a variable but for whole chunks of code.
    So remember a variable holds value but a function can hold one or 
    more complete lines of code.
 
//  So to use the function, we simply write the function name
	and this process here of basically using the function is called 
    invoking the function, running the function
    or calling the function.
    

//	thinking write function  (calling / running / invoking the function).


//	So usually when we write functions we also pass data into a function
	and additionally, a function can also return data as well which means
    to give us data back.
    
//	functions are actually just values.
	So just as a number or a string or a boolean value. So a function 
	is not a type, okay? It's not like a string or number type but it's 
	also a value. And so if it's a value, we can store it in a variable.
