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

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);
