We are required to write a JavaScript function that takes in an array of Numbers. The array of numbers can contain both positive as well as negative numbers.The purpose of our function is to find the sub array from the array (of any length), whose elements when summed gives the ... Read More

We are required to write a JavaScript function that takes in two numbers say m and n. Then function should calculate and return m^n.For example − For m = 4, n = 3, thenpower(4, 3) = 4^3 = 4 * 4 * 4 = 64 power(6, 3) = 216The code ... Read More

Suppose, we have an array of objects that contains information about some data storage devices like this −const drives = [    {size:"900GB", count:3},    {size:"900GB", count:100},    {size:"1200GB", count:5},    {size:"900GB", count:1} ];Notice like how the same size comes multiple times.We are required to write a function that takes ...

Suppose, we have an object of arrays like this −const obj = {    arr_a: [9, 3, 2],    arr_b: [1, 5, 0],    arr_c: [7, 18] };We are required to write a JavaScript function that takes in one such object of arrays. The function should construct an flattened and ... Read More

We are required to write a JavaScript function that takes in two comma separated strings. The first string is the key string and the second string is the value string, the number of elements (commas) in both the strings will always be the same.Our function should construct an object based ...

We are required to write a JavaScript function that takes in an array of numbers as the first argument and an upper limit and lower limit number as second and third argument respectively. Our function should filter the array and return a new array that contains elements between the range ... Read More

Suppose, we have an array of objects like this −const arr = [    {a: 1, b: 2},    {a: 3, b: 4},    {a: 5, b: 6} ];We are required to write a JavaScript function that takes in one such array of objects. The function should then map this ... Read More

We have an array that contains various objects. A few objects on this array have a date field (which basically is returned as a string from the server, not a date object), while for others this field is null.The requirement is that we have to display objects without date at ... Read More
