In JavaScript, scope is the set of variables, objects, and functions that you have access. In the other hand current context of your code.

Scope can be global, local, functional, public, private and lexical.

Lexical scope - A function within another function, the inner function has access to the scope in the outer function, this is called Lexical Scope or Closure - also referred to as Static Scope.

// Scope A
var myFunction = function () {
  // Scope B
  var name = 'Todd'; // defined in Scope B
  var myOtherFunction = function () {
 // Scope C: `name` is accessible here!

The difference between angular js service and factory.

Service and Factory both just a simple function. Service acts as a constructor function but Factory is really just a function that gets called, which is why we have to return an object explicitly. We can create & return anything that's why Factory is much more powerful and flexible.

reference: https://toddmotto.com/factory-versus-service

Here's example of Service

app.service('MyService', function () {
  this.sayHello = function () {
    console.log('hello');
  };
