Function Invoking

We can define function in two ways,

• Function Expression

var myMethod = function () {
  console.log('This is function expression');
};

Can be written in arrow syntax,

var myMethod = () => console.log('This is function expression');

• Function Declaration

function() {
  console.log('This is function declaration');
}

When we use the function declaration, it is hoisted. But the function expression does not get hoisted.

arguments

Javascript has a arguments in the function's execution context.
