// Example 1 
// Only y is hoisted

x = 1; // Initialize x, and if not already declared, declare it - but no hoisting as there is no var in the statement.
console.log(x + " " + y); // '1 undefined'
// This prints value of y as undefined as JavaScript only hoists declarations
var y = 2; // Declare and Initialize y


// Example 2 
// No hoisting, but since initialization also causes declaration (if not already declared), variables are available.

a = 'Cran'; // Initialize a
b = 'berry'; // Initialize b
console.log(a + "" + b); // 'Cranberry'
