JavaScript Function: Exercise-15 with Solution

Write a JavaScript function to compute the value of bn where n is the exponent and b is the bases. Accept b and n from the user and display the result.

Sample Solution: -

HTML Code:

<!DOCTYPE html>
<html>
<head>
<meta charset=utf-8 />
<title>Compute the value of bn where n is the exponent and b is the bases</title>
</head>
<body>
<body onload="updateClock(); setInterval('updateClock()', 1000)">  
</body>
</html>

JavaScript Code:

function exp(b,n)
{
        var ans = 1;
        for (var i =1; i <= n; i++)
        {
                ans = b * ans;        
        }
        return ans;

JavaScript: Tips of the Day

Shorten an array using its length property

A great way of shortening an array is by redefining its length property.

let array = [0, 1, 2, 3, 4, 5, 6, 6, 8, 9]
array.length = 4
// Result: [0, 1, 2, 3]

Important to know though is that this is a destructive way of changing the array. This means you lose all the other values that used to be in the array.
