        <h4>Introduction
      </header>
      <p>JavaScript is a cross-platform, object-oriented scripting language. It is a small and lightweight language.
        Inside a host environment (for example, a web browser), JavaScript can be connected to the objects of its
        environment to provide programmatic control over them.

        JavaScript contains a standard library of objects, such as Array, Date, and Math, and a core set of language
        elements such as operators, control structures, and statements. Core JavaScript can be extended for a
        variety of purposes by supplementing it with additional objects; for example:</p>
      <ul>
        <li>Client-side JavaScript extends the core language by supplying objects to control a browser and its
          Document Object Model (DOM). For example, client-side extensions allow an application to place elements on
          an HTML form and respond to user events such as mouse clicks, form input, and page navigation.</li>
        <li>Server-side JavaScript extends the core language by supplying objects relevant to running JavaScript on
          a server. For example, server-side extensions allow an application to communicate with a database, provide
          continuity of information from one invocation to another of the application, or perform file manipulations
          on a server.</li>
      </ul>

      <header>
        <h4>What you should know
      </header>
      <p>This guide assumes you have the following basic background</p>
      <ul>
        <li>A general understanding of the Internet and the World Wide Web (WWW).</li>
        <li>Good working knowledge of HyperText Markup Language (HTML).</li>
        <li>Some programming experience. If you are new to programming, try one of the tutorials linked on the main
          page about JavaScript.</li>
      </ul>
    </section>
    <section class="main-section" id="JavaScript_and_Java">
      <header>
        <h4>JavaScript and Java
      </header>
      <p>JavaScript and Java are similar in some ways but fundamentally different in some others. The JavaScript
        language resembles Java but does not have Java's static typing and strong type checking. JavaScript follows
        most Java expression syntax, naming conventions and basic control-flow constructs which was the reason why
        it was renamed from LiveScript to JavaScript.</p>
      <p>In contrast to Java's compile-time system of classes built by declarations, JavaScript supports a runtime
        system based on a small number of data types representing numeric, Boolean, and string values. JavaScript
        has a prototype-based object model instead of the more common class-based object model. The prototype-based
        model provides dynamic inheritance; that is, what is inherited can vary for individual objects. JavaScript
        also supports functions without any special declarative requirements. Functions can be properties of
        objects, executing as loosely typed methods.</p>
      <p>JavaScript is a very free-form language compared to Java. You do not have to declare all variables,
        classes, and methods. You do not have to be concerned with whether methods are public, private, or
        protected, and you do not have to implement interfaces. Variables, parameters, and function return types are
        not explicitly typed.</p>
    </section>
    <section class="main-section" id="Hello_world">
      <header>
        <h4>Hello world
      </header>
      <p>To get started with writing JavaScript, open the Scratchpad and write your first "Hello world" JavaScript
        code:</p>
      <div style="width:100vw;height:10%;background-color:rgb(10,10,10,0.1);padding:0.5em;amrgin:auto;">
        <code >function greetMe(yourName) { alert("Hello " + yourName); }
greetMe("World");</code>
      </div>
    </section>
    <section class="main-section" id="Declaring_variables">
      <header>
        <h4>Declaring variables
      </header>
      <p>You can declare a variable in three ways:
        With the keyword var. For example,</p>
      <div style="width:100vw;height:10%;background-color:rgb(10,10,10,0.1);padding:0.5em;margin:auto;">
        <code id="c">var x=42;</code>
      </div>
      <p>This syntax can be used to declare both local and global variables.

        By simply assigning it a value. For example,</p>
      <div style="width:100vw;height:10%;background-color:rgb(10,10,10,0.1);padding:0.5em;margin:auto;">
        <code >x=42;</code>
      </div>
      <p>This always declares a global variable. It generates a strict JavaScript warning. You shouldn't use this
        variant.

        With the keyword let. For example,</p>
      <div style="width:100vw;height:10%;background-color:rgb(10,10,10,0.1);padding:0.5em;margin:auto;">
        <code id="c">let x;</code>
      </div>
      <p>This syntax can be used to declare a block scope local variable. See Variable scope below.</p>
      <div
        style="width:100vw;height:10%;background-color:rgb(10,10,10,0.1);padding:0.5em;margin:10px auto;margin:auto;">
        <code>cost x;</code>
      </div>
    </section>
  </main>

Challenge: Technical Documentation Page - Build a Technical Documentation Page
Each .nav-link should have an href attribute that links to its corresponding .main-section (e.g. If you click on a .nav-link element that contains the text “Hello world”, the page navigates to a section element with that id).

Welcome to the community!

Please tell us what the problem is in your own words. Learning to describe problems is hard, but it is an important part of learning how to code. This could include the error messages you are receiving for the code.
Also, the more you say, the more we can help!

Happy coding! :slight_smile:
