JavaScript Hoisting

The mechanism of using variables and functions before their declarations by moving their declarations at the top of the code is called as hoisting in Javascript.

Example:

<!DOCTYPE html>
<html>
<head>
</head>
<body>
 
<script>  
document.write(mul(2,5,6));  
function mul(a,b,c)  
{  
return a*b*c;  
}  
</script>
 
</body>
</html>

Output:
