Learning a New Language is Fun!
Okay, so I woke up this morning ready to rock! So I went ahead and started my first lesson in Javascript with CodeSchool. I took all my notes and compiled them in a html file on my github repository that you can find here. I decided to create a file for every lesson that I am going through. You can download "Day1.html".
<!DOCTYPE html>

<title>Title of the document</title>

<script>
//* Lesson #1 *//
var trainWhistles = 3 //* Storing a value in a variable *//
trainWhistles = 9 //* Changing the value of the variable *//
trainWhistles = trainWhistles + 3 //* Changing the value of the variable *//
trainWhistles +=3 //* Different way to accomplish it *//
trainWhistles -=3 //* Substract 3 from the variable *//
trainWhistles++; //* Add 1 to the value *//
trainWhistles--; //*Substract 1 to the value *//
document.write("All of our trains have " + trainWhistles + " whistles!"); //* Renders "All of our trains have 12 whistles! *//
//* Lesson #2 *//
var welcome = "Welcome to Javascript Training Program"
var safetyTips = "Learn Carefully!"
document.write(welcome.length) //* Return the value of the lenght of the variable */
document.write(safetyTips.length > welcome.lenght) //* Return the "False" bolean value because safetyTips is shorter than welcome *//
</script>

I made sure to put annotations to explain what everything meant so people who are interested can follow along.
What I've learned today?
- Understanding JavaScript
- Creating Simple Scripts
- Assigning Variables, Strings and Arrays
- Using Functions
I literally feel like NEO after getting downloaded data directly into his brain in the movie the Matrix.
Outside of CodeSchool where I did the exercises to make sure I understood the content well, I found this really cool 12 minute video that explain very well everything that I've just learned. It is now in my watch list if I need a refresher tomorrow.
Conclusion
It a lot easier than one may think. All we have to do is to take baby steps everyday. To me, 30 minutes a day is all I can fit in my schedule for now. But multiply this by 365 days and I should be good enough within the next year or so :-)
