Let’s say, we are required to write a function, say parseEqualInterval() that takes in an array of Numbers of strictly two elements as the first argument and a number n as the second argument and it inserts n-1 equidistant entries between the actual two elements of the original array so ...

Let’s say, we are required to write a function, say isSame() that accepts a nested object and returns a boolean depending on the fact whether or not all the keys have the same values. When saying all the keys we mean all the last keys like if a key has ... Read More

We are required to write a function, say minMax() that takes in an array of Numbers and rearranges the elements such that the greatest element appears first followed by the smallest elements then the second greatest element followed by second smallest element and so on.For example −// if the input ...

Consider we have an array of Numbers that looks like this −const array = [3.1, 1, 2.2, 5.1, 6, 7.3, 2.1, 9];We are required to write a function that counts how many of the elements are in the array below / above a given number.For example, if the number is ... Read More

We have an array of objects like this −const arr = [    { value: 12, gap: 1 },    { value: 13, gap: 1 },    { value: 14, gap: 1 },    { value: 15, gap: 1 },    { value: 19, gap: 2 },    { value: ... Read More

We are required to write a function that takes in a string as the first and the only argument and constructs an object with its keys based on the unique characters of the string and value of each key being defaulted to 0.For example −// if the input string is: ... Read More

We are required to write a function splitNumber() that takes in a positive integer and returns an array populated with the place values of all the digits of the number.For example −//if the input is: const num = 2346; //the output should be: const output = [2000, 300, 40, 6];Let’s ... Read More

Let’s say, we have an array of string / number literals that contains some duplicate values like this −const array = ['day', 'night', 'afternoon', 'night', 'noon', 'night', 'noon', 'day', 'afternoon', 'day', 'night'];We are required to write a function groupSimilar() that takes in this array and returns a new array where ... Read More

We are required to write a function that, given an array arr and a number n, returns the array with elements repeating no more than n times. And we have to do all this without disturbing the indices of desired elements. So, let’s write the code for this function, We ... Read More

We are required to write an array function, say findMiddle that returns the middlemost element of the array without accessing its length property and without using any kind of built-in loops. If the array contains an odd number of elements, we return the one, middlemost element, or if the array ... Read More
