techLab - 1st Lesson

Install Git and download our Repo!

1. Go to your terminal (On Windows, it's called Command Prompt) and type:
   • Mac
   git --version
   • Linux
   sudo dnf install git-all Or, if you are on a debian based distribution, like Ubuntu: sudo apt-get install git-all
   • Windows
   Just click here and download the latest version:
2. Almost done. Now, copy this code, to download our repo. It's probably going to be in your Desktop. ;)
   cd Desktop

   ---

   git clone https://github.com/mrcolo/techLab.git
3. All done. Don't worry if you didn't understand any of the commands above. We will take time to understand why Git is so important.

Let's start, shall we?

---

If this is your first attempt with Javascript, welcome! Try to run this snippet and play with it, by changing the values of a and b.

In here, we are initializing two variables, a and b. To do this, we use the syntax:

var a = 1

---

A ''var'' can be anything. Let's define a few types.

This is a number.

var 👹 = 4

---

This is a number with a floating point.

var 🤕 = 4.567

---

This is a string.

var 👻 = "Hello techLab"

---

I got the variables. Now what?

---

Now we can start playing with Javascript. Try to edit this snippet to use mathematical operations , such as multiplication, division, or subtraction, to compute stuff out.

---

Conditions

---

A condition allows us to check whether an expression is true, or false. Let's see a basic example:

Try to edit this snippet to make it evaluate the two numbers as equal!

---

Objects

---

Now let's go into something a little more specific. What's an object?

An object has many categories that we can access to. Think about it as a car. A car is formed by a bunch of things, such as engine, wheels, and so on. Here's what an object looks like in JS:

Now, what if you bought a Yoga Subscription? Try to change the object's name and categories (such as Subscription or Address)to make it look like a Yoga Subscription Object!

Cool Stuff - A good way to end our lesson.

---

With Javascript, we can interact with the web. Here's an example:

This is how alerts work. We are gonna use them, so you should probably get the gist of it. Also! They are gonna look a bit different depending on your favorite browser.

Try to play with the snippet to display a different alert. Remember, you can display everything, from numbers to strings. Wait. What if you wanted to use an object?

---

Hey. What's the time?

Javascript knows exactly what time it is. You just have to know how to ask him, or her, or non-gender conforming computer, how to.

---

All done. Did it hurt?

---

This is what we learnt, so far, today.

• How to write cool variables with Javascript. var myAwesomeString = "Thanks for being here, Lancers 👨🏻‍🚀 "
• How to check if something is true or false using an if statement. if(thisIsTrue) {console.log("This works!")}
• How to create an object! var myAwesomeObject = {isThisOver: true}
• How to create alerts and display the current time. var date = new Date() alert(date)

Take Away Project 🌮🌮

Create a Celsius to Fahreneit converter. Display the result on an alarm that tells the current time too.
