We are required to write a JavaScript function that takes in a Number, say n, and we are required to check whether there exist such three consecutive natural numbers (not decimal/floating point) whose sum equals to n. If there exist such numbers, our function should return them, otherwise ...
The number entered by the user is stored in a temp variable. And a while loop is used to iterate until its value is less than 0. Each digit of the number is raised to the power of the length of the number. Also Read: JavaScript Program to Find Armstrong Number in an Interval Before...
It returns the 'number' string if you use it on a number value:typeof 1 //'number' const value = 2 typeof value //'number'So you can do a conditional check like this:const value = 2 if (typeof value === 'number') { //it's a number }...
const colors = ['red', 'green', 'blue']; console.log(0 in colors); // true console.log(3 in colors); // false console.log('length' in colors); // true Arrays are objects in JavaScript, so we can check for index existence. Note that 'length' is a built-in array property. ...
Here, we are going to learn how to check whether a given number is palindrome or not in JavaScript.
In JavaScript, null represents an intentional absence of a value, indicating that a variable has been declared with a null value on purpose. On the other hand, undefined represents the absence of any object value that is unintentional. A null check determines whether a variable has a null valu...
Here’s my solution in Typescript. sumDigits(str: string): number { if(str.length == 0) { return 0; } var sum = 0; let charArray = str.split(""); charArray.forEach((val) => { let num = parseInt(val); if(!isNaN(num)) { sum += num; } }); return sum; } The solut...
