/*With respect to*/ (...args) =>//, ...args is a rest parameter. 
//It always has to be the last entry in the parameter list and 
//it will be assigned an array that contains all arguments that 
//haven't been assigned to previous parameters.

//It's basically the replacement for the arguments object. Instead of writing:

function max() {
  var values = Array.prototype.slice.call(arguments, 0);
  // ...
}
max(1,2,3);

//you can write

function max(...value) {
  // ...
}
max(1,2,3);

/*Also, since arrow functions don't have an arguments object, 
this is the only way to create variadic (arrow) functions.*/
