13. How the web works
Type a URL from a client (e.g. google.com)
Browser sends an HTTP request asking for specific files
Browser receives those files and renders them as a website
bit.ly/introjs-sd
Wi-Fi: Deskhub-main
Pass: Create2017! 7
14. On a basic level, the web works through communication between a browser like google chrome and a server. The user enters a web address like
google.com into a browser and hits enter. Then the browser sends a request to the server that has the files for google.com on it. And the server
sends back those files to the browser to load.

15. Client/Servers

16. A browser, also called the client, can be anything that connects to the internet. Your laptop, your phone, all those things are clients. They’re
responsible for sending requests and loading the pages from files sent back from the server. It manages what the app looks like. This is the
responsibility of a frontend developer. The server holds all those files. Its job is to shoot specific files to the client based on its requests. It manages
what the app actually does and is the responsibility of the backend developer

18. Let's break it down with an example. Let's say I log into facebook. When I try to go to that page, my computer is going to send a request to
facebook’s server. Facebook’s server is going to look at that request and think, “okay, what should I send back to ${your name}’s computer?” Its
going to look through my friend’s posts and determine using an algorithm what’s most important to put in my feed. Then it’ll send all that info,
including the files to display the info, to my computer. My computer will then read and interpret those files and display the information on my screen.

20. History of Javascript
Written by Brendan Eich in 1995 for Netscape
Initial version written in 10 days
Completely unrelated to Java, but maybe named after it to
draft off its popularity
Over 10 years, became default programming language for
browsers
Continues to evolve under guidance of ECMA International,
with input from top tech companies

21. Javascript was initially written by Brendan Eich in 1995 for Netscape. It was written in 10 days but has since been improved. A common
misconception is that it has something to do with Java, but they are very different languages. Most likely, Javascript was given its name to ride the
wave of popularity that Java had at the time. In the ten years after it was created, it grew in popularity and today it has a monopoly on front end web
development as the default language for web programming. It continues to evolve under the guidance of the ECMA International, with input from top
tech companies.

23. Because of its immense popularity, javascript today has an enormous community of developers, libraries, and frameworks. Because of its
widespread use, it also has tons of job opportunities. The syntax is also easier to understand compared to other programming languages making it a
good place to start for first-timers.

bit.ly/introjs-sd
Wi-Fi: Deskhub-main
Pass: Create2017! 13
25. The first important concept in Javascript is the use of variables. A variable is a container used to store data values. In javascript, we define a variable
by first typing out ‘var’. This tells the computer that we’re about to make a variable. Then we type the variable’s name. This can be anything you
want, but it is helpful if the name of the variable corresponds to its value. Then we put an equal sign and type in the value of that variable. The
computer now recognizes that the variable numberOfSheep is equal to 20.
Speaker notes
27. I’m going to show you a few examples of variables you can create.
var numberOfSheep = 20;
console.log(numberOfSheep);
var nameOfSheep = “Fred”;
console.log(nameOfSheep);
var cars = 5;
var trucks = 6;
var vehicles = x + y;
console.log(vehicles);
var foo = ‘foo’;
var bar = ‘bar’;
var something = x + y;
console.log(something);

28. Declaring a function with Javascript
function greet() {
return "Hello world!";
}

Wi-Fi: Deskhub-main
Pass: Create2017! 15
29. A function is a piece of code that’s meant to perform a specific task. You create a function by first typing out the word ‘function’. This tells the
computer that you’re about to write a function. Then we write out the name of the function followed by parentheses. You don’t need to know quite yet
what the parentheses do, just that they are required to be placed immediately after the function name. Then, inside curly brackets, we state what the
function is going to do. In this case the function will simply return the string or statement “Hello world!”. Return is a word used inside a function that
means ‘give back this value’.
Speaker notes
31. I’m going to show you a few examples of functions you can create
function adder() {
console.log(2 + 3);
}
adder();
---erase console.log and put return---
function adder() {
return 2 + 3;
}
adder();
console.log(adder());
var subtractor = function() {
return 5 - 2;
}
console.log(subtractor());
var subtractorVariable = subtractor();
console.log(subtractorVariable);

32. If/Else Statements
go to gas stationkeep driving
if false if true
need gas?
family roadtrip
bit.ly/introjs-sd
Wi-Fi: Deskhub-main
Pass: Create2017! 17
33. Functions can also contain some logic to them that allow them to make decisions based on different circumstances. This logic is contained inside
if/else statements. For example, let's say you’re on a roadtrip. You ask yourself, do I need gas. If it's true that you need gas, you should go to the gas
station. If it's false that you need gas, then you continue driving. This is a very simplified version of an if/else statement.
Speaker notes
35. If we were going to make that into a function, we could write it this way. The name of our function is familyRoadtrip. The first line is our if statement.
We needGas is true, then we getGas. Else, we keep driving. This set of equal signs here is called a comparison operator. It's used to compare two
values to see if they’re equal.
Speaker notes
37. There are a few comparison operators you can use in Javascript. Another one is the ‘not equal to’ sign. Here you can see how, when we compare 5
and 6, the results true and false change depending on the operator.
Speaker notes
39. Here’s an example of an if/else statement.
function comparison() {
if (5 == 6) {
console.log("Math is broken");
}
else {
console.log("Math is working today");
}
}
comparison();
To show additional if statements, add this:
if (5 == 5) {
console.log("Math is definitely working today");
}
To show additional comparison operators, add this:
if (5 < 6) {
console.log("And five is still less than 6");
}
if (5 >= 5) {
console.log("And five is still 5");
}

41. Finally, functions allow us to use values outside of them by passing them in as parameters. Here, you see that we’ve put parameters ‘a’ and ‘b’
inside the parentheses. They correspond to the ‘a’ and ‘b’ inside the function. If we were to call the function like so, the number one would
correspond to ‘a’, and the number 2 would correspond to ‘b’.

console.log(first + second);
}
concatenator(‘foo’, ‘bar’);
function checker(param1, param2) {
if (param1 == param2) {
console.log(param1 + " is equal to " + param2);
}
else {
console.log("They are not equal");
}
}
checker(4,4);

44. Real developers use Google... a lot
bit.ly/introjs-sd
Wi-Fi: Deskhub-main
Pass: Create2017! 23
45. Google is an everyday part of being a developer. A key part of becoming a developer is getting comfortable using Google to learn and look up things.
The more you code, the more you will use Google, not the other way around. When you get stuck tonight, or whenever, make sure to Google it first!
Speaker notes
47. Go ahead and go to this link. This will take you to a site called repl.it. Repl is a site that allows us to write code and instantly see a result. Sign up for
repl and enter the classroom called Intro to Javascript.
Just to get you all familiar with the assignments, I’ll work through the first one with you. Click on Defining Variables and you should see a screen like
this.
First thing we should do is read the directions on the right side of the screen. They say:
“The function sayingHi needs two parameters to function. The variables at the top aren't yet defined so when we try to call sayingHi on line 8, the
function fails.
Define the variables so that when the function runs, it prints 'Hello World'. Define a as 'Hello' and b as 'World'. Don't forget your quotes!
Don't change the test code at the bottom of the file. That's there to help make sure you're code is responding correctly. The console will respond with
'SUCCESS: `sayingHi` is working' if you wrote the function correct, and will print 'FAILURE: `sayingHi` is not working' if your function is not correct.
“
Right now, when we press run at the top, it gives us some errors. So, the assignment needs us to define some variables. As good developers, if
there’s something we don’t know how to do, we google it. So, lets Google, how to define variables in javascript. Lets click on the first one. This is
w3schools, a really nice site for information on programming and javascript. Okay, so we can define this variable x by saying = and then the number
5. Well, that’s all well and good, but I need to put a word in there, not a number. Let's see if they have an example for defining a variable with a word.
I’ll just scroll down and see. Okay, so here’s a variable that has a word as a definition. The word is in quotes because its a string. Lets go back to our
code and try putting in “hello” and “world” in there with quotes. It works!
Go ahead and start working on the remaining challenges. Again, don’t hesitate to Google. Its’ your best friend. The first couple challenges are easier
than the last few so if you can’t get them all tonight, that’s okay.
Speaker notes
50. If you’re interested in becoming a developer, however, you’ll want to consider a bootcamp.
Bootcamps are short programs that provide the structure and support to help people become developers.
The reason bootcamps emerged, massive gap between growing demand for software developers and supply
Bootcamps were created to fill that gap: 73% get jobs as developers with an average salary lift of $26K.

54. We’ve been able to achieve these results because of the unprecedented support our students receive: Thinkful students work through the program
with their own personal mentor.
As you might have seen today, learning in a classroom was much harder than just individually with your TA. We saw the same problem and that's
why all our programs are built around 1:1 support
Mentors have 10+ years of experience, work at companies like Home Depot, Delta, etc
You also have Slack + QA sessions if you’re stuck at 2AM
Not only do you have a technical mentor you also have a career mentor, who taps into our network of mentors and employers to get you interviews
and help you prepare for them.
And then we have a local community: dinners and networking to meet other students, mentors, and resources for Thinkful here in San Diego
