Hoisting is JavaScript’s default behavior of moving declarations to the top.

In JavaScript, a variable can be declared after it has been used.

In other words; a variable can be used before it has been declared.

x = 5; // Assign 5 to x
 
elem = document.getElementById("demo"); // Find an element
elem.innerHTML = x;                     // Display x in the element
 
var x; // Declare x
