We are required to write a JavaScript function that calculates the nth root of a number and returns it.ExampleThe code for this will be −const findNthRoot = (m, n) => {    try {       let negate = n % 2 == 1 && m < 0;       if(negate)          m = −m;       let possible = Math.pow(m, 1 / n);       n = Math.pow(possible, n);       if(Math.abs(m − n) < 1 && (m > 0 == n > 0))       return negate ? −possible : possible;    } catch(e){       return null;    } }; console.log(findNthRoot(45, 6));OutputAnd the output in the console will be −1.8859727740585395

The problem statement says to perform sorting of an array of objects taking in one specific condition to sort null value key pairs present in the array of objects to be pushed at the end of the array where the array of objects is given by the user as an input source. What is an Array in JavaScript ? If you are familiar with any other programming language like C, C++, or Java, you must have heard the term 'array.' In programming, an array is a collection of similar data elements under one roof. Now, an important question ... Read More

The problem statement says to perform a complete conversion of array of objects into an object of arrays in JavaScript where array of objects are given as an input source by the user and given input can be totally converted into the resultant object of arrays successfully. What is an array in JavaScript ? If you are familiar with any other programming language like C, C++, or Java, you must have heard the term 'array.' In programming, an array is a collection of similar data elements under one roof. Now, an important question arises: if arrays are generally the ... Read More

We are required to write a JavaScript function that takes in a number. The function should divide the number into chunks according to the following rules −The number of chunks should be a power−of−two, Each chunk should also have a power-of-two number of items (where size goes up to a max power of two, so 1, 2, 4, 8, 16, 32, 32 being the max)Therefore, for example, 8 could be divided into 1 bucket −[8]9 could be −[8, 1]That works because both numbers are powers of two, and the size of the array is 2 (also a power of two).Let's ...

Suppose, we have an array of objects containing some data about some users like this −const arr = [    {       "name":"aaa",       "id":"2100",       "designation":"developer"    },    {       "name":"bbb",       "id":"8888",       "designation":"team lead"    },    {       "name":"ccc",       "id":"6745",       "designation":"manager"    },    {       "name":"aaa",       "id":"9899",       "designation":"sw"    } ];We are required to write a JavaScript function that takes in one such array. Then our ... Read More

Suppose, we have an array of two numbers that specify a range. We are required to write a function that finds the smallest common multiple of the provided parameters that can be evenly divided by both, as well as by all sequential numbers in the range between these parameters.The range will be an array of two numbers that will not necessarily be in numerical order.For example, if given [1, 3], then we are required to find the smallest common multiple of both 1 and 3 that is also evenly divisible by all numbers between 1 and 3. The answer here ... Read More

Suppose, we have a JSON array of objects like this −const arr = [    {       "id": "03868185",       "month_10": 6,    },    {       "id": "03870584",       "month_6": 2,    },    {       "id": "03870584",       "month_7": 5,    },    {       "id": "51295",       "month_1": 1,    },    {       "id": "51295",       "month_10": 1,    },    {       "id": "55468",       "month_11": 1,    } ];Here, we ...

Suppose, we have two arrays of objects like these −const arr1 = [    {name:'test', lastname: 'test', gender:'f'},    {name:'test1', lastname: 'test1', gender:'f'},    {name:'test2', lastname: 'test2', gender:'m'} ]; const arr2 = [    {name:'test21', lastname: 'test21', gender:'f'},    {name:'test1', lastname: 'test1', gender:'f'},    {name:'test2', lastname: 'test2', gender:'m'},    {name:'test22', lastname: 'test22', gender:'m'} ];These arrays do not have any repeating objects within (repeating on the basis of 'name' property) but there exist some objects with repeating names in the first and second objects.We are required to write a JavaScript function that takes two such arrays and returns a new array.The ...

We are required to write a JavaScript function that takes in two sorted array of numbers. The function should merge the two arrays together to form a resultant sorted array and return that array.For example −If the two arrays are −const arr1 = [2, 6, 6, 8, 9]; const arr2 = [1, 4, 5, 7];Then the output array should be −const output = [1, 2, 4, 6, 6, 7, 8, 9];ExampleThe code for this will be −const arr1 = [2, 6, 6, 8, 9]; const arr2 = [1, 4, 5, 7]; const mergeSortedArrays = (arr1 = [], arr2 = []) ...

In this article, we will learn to prepend a string into all the values of an array in JavaScript. Arrays are versatile data structures used to store multiple elements of similar or mixed types. A common operation is prepending a string to each element of an array, which involves adding a specified string at the beginning of each element. Problem Statement The problem statement can be deeply visualized as given a string text specifically to prepend or attach at the beginning of each element of the array , the output should return the new resultant array with prepended string value ...
