Node.js ECMAScript 2015 (ES6) with Node.js const/let declarations
Example
Unlike var, const/let are bound to lexical scope rather than function scope.
{
var x = 1 // will escape the scope
let y = 2 // bound to lexical scope
const z = 3 // bound to lexical scope, constant
}
console.log(x) // 1
console.log(y) // ReferenceError: y is not defined
console.log(z) // ReferenceError: z is not defined
