JavaScript variables: var and let and const

My inner pedant really hates this first sentence:

> There are three ways to create variables in a JavaScript application: using var, using let, or using const.

No. There are two ways to create variables (let, var), and _one_ way to create a constant (const).

Your inner pedant isn't being pedantic enough, then, because the ES spec defines them all as variables.

> 13.3.1 Let and Const Declarations

> NOTE let and const declarations define variables that are scoped to the running execution context’s LexicalEnvironment.

They're not really constant though, if you wanna be really pedantic. You can modify a const object for example.

It’s constant because it cannot be reassigned - but it is not immutable.
