Harshad numbers are those numbers which are exactly divisible by the sum of their digits. Like the number 126, it is completely divisible by 1+2+6 = 9.All single digit numbers are harshad numbers.Harshad numbers often exist in consecutive clusters like [1, 2, 3, 4, 5, 6, 7, 8, 9, 10], ...

Our job is to create a function, say createRandom, that takes in two argument and returns a pseudorandom number between the range (max exclusive).The code for the function will be −Exampleconst min = 3; const max = 9; const createRandom = (min, max) => {    const diff = max ... Read More

We have to create a function that takes in 2 arguments: an integer and an array of integers. First argument denotes the length of array we have to return and the second argument contains the elements that should not be present in our return array. Actually, we need an array ... Read More

It is a well-known dilemma that when we use includes() inside nested arrays i.e., multidimensional array, it does not work, there exists a Array.prototype.flat() function which flats the array and then searches through but it’s browser support is not very good yet.So our job is to create a includesMultiDimension() function ...

Suppose, we have two arrays both containing three elements each, the corresponding values of red, green, blue color in integer.Our job is to add the corresponding value to form an array for new rgb color and also making sure if any value adds up to more than 255, we that ... Read More

Let’s say we are required to write a function that accepts a string and capitalizes the first letter of every word in that string and changes the case of all the remaining letters to lowercase.For example, if the input string is −hello world coding is very interestingThe output should be ...

We are given an array of integers and told that all the elements appear for an even number of times except a single element. Our job is to find that element in single iteration.Let this be the sample array −[1, 4, 3, 4, 2, 3, 2, 7, 8, 8, 9, ... Read More

We have the following arrays of objects, we need to merge them into one removing the objects that have redundant value for the property name −const first = [{    name: 'Rahul',    age: 23 }, {    name: 'Ramesh',    age: 27 }, {    name: 'Vikram',    age: ... Read More
