 ## What is computer programming?
 
-Broadly, computer programming is telling a computer exactly what to do. This is done using a procedural syntax popularly referred to as **code**, which combines special words, signs, and symbols.

 # Conditional evaluation
 
+
 Like variables, conditional evaluation is one of the key concepts you'll come across in programming. It is used to execute a certain action based on matched conditions.

 Bash gives you four conditional keywords `if`, `elif`, `else` and `fi`.
 
 1. Conditional evaluations must start with an `if` and end with an `fi`

+# Choosing a programming language
+
+Before we begin this section, I would like to congratulate you for getting past
+the preliminary concepts section --- that's module 1 -- 7. In this section, our
+focus would be on programming! Let's being!
+
+In a sense, choosing your first programming language can be a bit like choosing
+your first car, you'd want something which is comfortable and not overpriced.
+Here are some key things you should know before choosing a language
+
+<dl>
+<dt class="bold-strong"> 1. The end goal</dt>
+<dd> What you intend to achieve or the domain you want to programming in </dd>
+
+<dt class="bold-strong"> 2. Adoption</dt>
+<dd> When you build applications or software, you'd run into issues and in need of help, it's great to choose a language adopted for the domain, for instance using Golang for embedded software might be wrong, as of the time of this writing  </dd>
+
+<dt class="bold-strong"> 3. Learning curve</dt>
+<dd> While this isn't exactly a problem when you have excess time, a steep learning curve mean you need to do more groundwork to understand some concepts</dd>
+</dl>
+
+Now, let's try to answer those questions,
+
+1. The end goal: The end goal of this book is to teach you core programming
+   concepts and make you a backend engineer.
+2. Adoption: I have carefully selected 4 programming languages used for backend
+   applications
+3. Learning curve: The 4 available languages have different learning curves
+   discussed below;
+
+## Learning Curves
+
+When we discussed the
+[classification of programming languages](../module_1/classification_of_programming_languages.md#classification-of-programming-language),
+I mentioned 2 classes, compiled and interpreted languages, allow me to extend it
+further to include, statically typed languages and dynamically typed languages;
+
+### Statically typed languages
+
+In statically typed languages, the programmer is often required to expressively
+indicate the type of a
+[variable](../module_5/scripts/using-variables.html?highlight=variable#using-variable).
+This mean you must state if your variable is a number or letters or something
+else, and example of such in this resource is Rust and Golang.
+
+### Dynamically typed languages
+
+In dynamically typed language like JavaScript and Python, it is relatively easy
+to get to speed, compared to statically typed languages. However, down the lane
+the learning becomes hard to quantify and it seems as if learning is standstill.
+
+Broadly, statically typed languages are longer to be established in and master
+but they make it easier to learn other statically typed languages and the
+dynamically typed ones rather quickly.
+
+## Which language should you choose?
+
+The short answer is anyone is fine.
+
+Long answer, I've used Rust and JavaScript in and out of work environment and I
+can say for a fact that It's always best to know both, personally, I prefer
+statically typed language for medium to large-size projects, while I used
+JavaScript for small size application, scripting and prototyping.
+
+At the end So learning one and switching to the other is fine, one thing you
+must not doing when starting out is learning two languages concurrently, it's
+usually difficult.
+
+In the next module, I encourage you to choose one of the four languages and
+stick it to the end of the material for effective learning
