// 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'hoisting meaning javascript
x = 1;
alert('x = ' + x); // display x = 1
var x;How does javascript hoisting works?
console.log(num); // Returns 'undefined' from hoisted var declaration (not 6)
var num; // Declaration
num = 6; // InitializationCopyright © 2021 Codeinu
