Join Eve Porcello for an in-depth discussion in this video Symbols, part of Learning ECMAScript 6.
For now, let's take a look at how we can create symbols…using the factory function.…So, here in our file, we're going to create…a new variable called id…and we're going to set this equal to a symbol.…So symbol is going to be a capital S…and we're going to create it by using this factory function.…Factory functions are simply functions that create things,…in this case, a symbol.…Let's then go ahead and create an object called courseInfo…and our courseInfo object is going to have a key…let's see, let me add my semicolon here,…and on line 10, and then on line nine here,…we'll give it a title which is ES6…
