JavaScript: Compute the value of bn where n is the exponent and b is the bases

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;
}
console.log(exp(2, 3));

Sample Output:

8

JavaScript: Tips of the Day

How to check whether a string contains a substring in JavaScript?

ECMAScript 6 introduced String.prototype.includes:

const string = "foo";
const substring = "oo";

console.log(string.includes(substring));

includes doesn't have Internet Explorer support, though. In ECMAScript 5 or older environments, use String.prototype.indexOf, which returns -1 when a substring cannot be found: 

var string = "foo";
var substring = "oo";

console.log(string.indexOf(substring) !== -1);
