+# Linked Lists 
+
+In all programming languages, there are data structures. One of these data structures are called Linked Lists. There is no built in method or function for Linked Lists in Javascript so you will have to implement it yourself. 
+
+A Linked List is very similar to a normal array in Javascript, it just acts a little bit differently. 
+
+In this chapter, we will go over the different ways we can implement a Linked List. 
+
+Here's an example of a Linked List: 
+
+```
+["one", "two", "three", "four"]
+```

+# Add

+What we will do first is add a value to a Linked List.

+```js 
+class Node {
+    constructor(data) {

+        this.next = null

-JavaScript (_JS for short_) is the programming language that enables web pages to respond to user interaction beyond the basic level. It was created in 1995, and is today one of the most famous and used programming languages.
+JavaScript, often abbreviated JS, is a programming language that is one of the core technologies of the World Wide Web, alongside HTML and CSS. As of 2022, 98% of websites use JavaScript on the client side for webpage behavior, often incorporating third-party libraries.
+
+Do not confuse JavaScript with the Java programming language. Both "Java" and "JavaScript" are trademarks or registered trademarks of Oracle in the U.S. and other countries. However, the two programming languages have very different syntax, semantics, and use.
