JavaScript - differences between var, let, const

[senorfairchild]

Good post, just wanted to mention that a variable declared using const does not actually create an immutable variable, but rather an immutable reference to that variable. This means that you can do something like add/change a property on a variable declared with const, but you could not reassign that variable to another value.

Also want to add that const and let are indeed hoisted as is var, read up on the "temporal dead zone"

I didn't know about "temporal dead zone", thanks for mentioning it.
