Insertion of a specific character after every n characters in Javascript is an easy to understand concept and gives us a better understanding about Javascript's functions. Here n can be any whole number ranging from 1 to less than the length of the string. In this article we will deal with a variable inputString = "abcdefghijklmnopqrstuvwxyz, " and aim to append a "-" character after every 5 characters. There are several ways to accomplish this with JavaScript, which are as follows − Making use of the slice() method In JavaScript, the slice() function is used to extract a portion of ... Read More

In this article, we are going to discuss how to increment a given date using JavaScript. First, we will analyse and understand what is meant by this. Given a certain date x = “05-02-2023”, we want to add y = 7 days to this date and print the resulting date which is “12-02-2023”. As a human we can manually add 7 days to 5th February and get the resultant. But we need JavaScript to do this programmatically for us. There are few techniques to do so which we shall be discussing in this article. Using addDays() function The addDays function ... Read More

A linked list is a data structure that consists of a sequence of elements, each of which contains a reference (or "link") to the next element in the sequence. The first element is called the head and the last element is called the tail. Linked lists have many advantages over other data structures. Now we shall look at how to implement Linked list using JavaScript.
