We are required to write a JavaScript function that takes in an array of Numbers with positive as well as negative numbers and returns the maximum products of two numbers in one traversal.Let's write the code for this function −Exampleconst arr = [-1, -3, -4, 2, 0, -5]; const arr2 ... Read More

We are required to write a JavaScript function that takes in an array of numbers and returns an array with all even numbers appearing on the left side of any odd number and all the odd numbers appearing on the right side of any even number.Therefore, let's write the code ... Read More

We are required to write a JavaScript function that accepts two strings and a number n. The function matches the two strings i.e., it checks if the two strings contains the same characters.

We are required to write a JavaScript function that takes in two objects (possibly nested) and returns a new object with key value pair for the keys that were present in the first object but not in the secondLet's write the code for this function −Exampleconst obj1 = {   ... Read More

We are required to write a JavaScript function that takes in a string with repetitive characters and returns a new string in which all the same characters are exactly n characters away from each other. And the number should be smaller than the length of the array.For example −If the ... Read More

We have an array of arrays that contains the marks scored by some students in some subjects −const arr = [    ['Math', 'John', 100],    ['Math', 'Jake', 89],    ['Math', 'Amy', 93],    ['Science', 'Jake', 89],    ['Science', 'John', 89],    ['Science', 'Amy', 83],    ['English', 'John', 82],   ...

We are required to write a JavaScript function that takes in a string and a number n as two arguments (the number should be such that it exactly divides the length of string). And we have to return an array of n strings of equal length.For example −If the string ... Read More

We are required to write a JavaScript function that takes in an array of Numbers with some positive and negative values. We are required to determine whether there exists a subarray in the original array whose net sum is 0 or not.Our function should return a boolean on this basis.ApproachThe ... Read More
