If you are still looking for confidence with JavaScript, I highly recommend you read the other titles in this series first:

Up & Going: Are you new to programming and JS? This is the roadmap you need to consult as you start your learning journey.

• Up & Going
• Scope & Closures
• this & Object Prototypes
• Types & Grammar
• Async & Performance

If you’ve already read all those titles and you feel pretty comfortable with the topics they cover, it’s time we dive into the evolution of JS to explore all the changes coming not only soon but farther over the horizon.

let Declarations

However, we can now create declarations that are bound to any block, called (unsurprisingly) block scoping. This means all we need is a pair of { .. } to create a scope. Instead of using var, which always declares variables attached to the enclosing function (or global, if top level) scope, use let:

var a = 2;

{
    let a = 3;
    console.log( a );   // 3
}

console.log( a );       // 2
