Let’s say, we are required to write a JavaScript function that takes in an array of Numbers and returns a new array with elements as sum of two consecutive elements from the original array.For example, if the input array is −const arr = [3, 6, 3, 87, 3, 23, 2, ... Read More

We have an array of literals like this −const arr = [56768, 5465, 5467, 3, 878, 878, 34435, 78799];We are required to write a JavaScript function that takes in this array and a number n and if the corresponding element contains more than or equal to n characters, then the ... Read More

We are required to write a JavaScript function that takes in an array of numbers like this −const arr = [3, 6, 34, 12, 6, 8, 8, 5, 6, 8];The function should return the difference between the sum of elements present at the odd index and the sum of elements ... Read More

We are required to write a JavaScript function that accepts two string and a number n.The function matches the two strings i.e., it checks if the two strings contains the same characters.The function returns true if both the strings contain the same character irrespective of their order or if they ...

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

Let’s say, we have an array of Numbers that contains only 0, 1 and we are required to write a JavaScript function that takes in this array and brings all 1s to the start and 0s to the end.For example − If the input array is −const arr = [1, ... Read More

Let’s say, we are required to write a JavaScript function that takes in a string and returns a new string with words rearranged according to their increasing length.ExampleFollowing is the code −const str = 'This is a sample string only'; const arrangeByLength = str => {    const strArr = ...

Conventionally, we have functions like parseInt() and parseFloat() that takes in a string and converts the number string to Number. But these methods fail when we have numbers embedded at random index inside the string.For example: The following would only return 454, but what we want is 4545453 −parseInt('454ffdg54hg53')So, we ...
