Suppose, we have a nested array of arrays like this −const arr = [    ["LEFT", "RIGHT", "RIGHT", "BOTTOM", "TOP"],    ["RIGHT", "LEFT", "TOP"],    ["TOP", "LEFT"] ];We are required to write a JavaScript function that takes in one such array. The function then should pick the smallest subarray (smallest ... Read More

Suppose, we have an array of objects like this −const arr = [    { Phase: "Phase 1", Step: "Step 1", Task: "Task 1", Value: "5" },    { Phase: "Phase 1", Step: "Step 1", Task: "Task 2", Value: "10" },    { Phase: "Phase 1", Step: "Step 2", Task: ... Read More

We have got an array of objects. If one property of the object is the same as in another object, we consider it to be a duplicate entry.We want to group objects by this property and store information about how many times the "duplicate" occurred.   X A B O   ... Read More

We have a set of vertical regions defined by y1 and y2 coordinates, where y1 is the starting point and y2 is the ending point of each region.The origin of our coordinates system is the top-left corner, so y2 is always greater than y1.This is an example −const regions = ... Read More

Suppose we have two arrays describing some cashflow like these −const months = ["jan", "feb", "mar", "apr"]; const cashflows = [    {'month':'jan', 'value':10},    {'month':'mar', 'value':20} ];We are required to write a JavaScript function that takes in two such arrays. Our function should then construct a combined array of ... Read More

Suppose, we have two JavaScript objects defined like this −const a = {    a: 1,    af: function() { console.log(this.a) }, }; const b = {    b: 2,    bf: function() { console.log(this.b) }, };We are required to write a JavaScript function that takes in two such objects. ... Read More

Let’s say, we have an array of numbers and we added elements to it. You need to devise a simple way to remove a specific element from an array.The following is what we are looking for −array.remove(number);We have to use core JavaScript. Frameworks are not allowed.ExampleThe code for this will ... Read More

We are required to depict the ways in which we can access the current timestamp in JavaScript in −---seconds---millisecondsJavaScript works with the number of milliseconds since the epoch whereas most other languages work with the seconds.This will give you a Unix timestamp (in seconds) −const date = new Date(); const ...
