Read MoreAdd all records from one array to each record from a different array in JavaScript
The problem statement asks the user to add all the records from one array to each record from a different array in JavaScript , the just read statement seems tough to understand and implement code upon . The simplest meaning is given two arrays of different collections of values , we need to generate a combined new array of objects such that the new generated array is a collection of every possible of values present in both arrays for say array1 and array2. The problem statement can be implemented in another way too , saying to find the Cartesian ...
Read MoreConvert number to characters in JavaScript
In the given problem statement we are asked to convert numbers to characters with the help of javascript functionalities. In Javascript we have some built−in functions to convert a number to its corresponding characters and also with user defined functions we can convert it. Logic for The Above Problem As we know that every programming language defines its own function to perform certain operations. So Javascript has a built−in method to convert a number into its corresponding character. These function names are 'fromCharCode' and 'charCodeAt'.

Read MoreCheck if items in an array are consecutive but WITHOUT SORTING in JavaScript
In the above statement we are asked to check if items in an array are consecutive without sorting the array with the help of javascript functionalities. We can solve this problem with some basic functionalities of javascript. Let us see how to do this! What are Consecutive Items in an Array ? Consecutive elements means every next item should be greater or smaller to the previous element in the sequence. For example we have an array [1, 2, 3, 4, 5], So here we can see that the array contains all the consecutive items as they are in increasing ...
Read MoreCalculating the average for each subarray separately and then return the sum of all the averages in JavaScript
In the given problem statement we are asked to calculate the average for each subarray separately and then return the sum of all the averages with the help of javascript functionalities. As we talk about average for subarrays we can use the reduce method of javascript. What is the reduce() Method in JavaScript ? Let's understand the working of a reduce function in JavaScript. In javascript the reduce method is used to reduce an array to a single value by iterating over each and every item of the array. And by applying the callback function that accumulates a value based ...
