A summary of commands and syntax which we've learnt so far

Git

Scenario 1: Cloning another repo

On github.com, go to the repo which you'd like to clone (e.g. http://www.github.com/davified/js-functions)
Fork the repo by clicking on the 'Fork' button on the top right corner of the page
In your terminal, cd to a folder where you want to keep this repo (e.g. Desktop/coding/week-1), and run
```
git clone http://www.github.com/YOUR_GITHUB_USERNAME/js-functions
```
You'll now have the repo running on your local machine! Awesome! After making changes to the files, run the following commands to commit and push your changes to github:
```
git add -A
git commit -m "your awesome commit message"
git push -u origin master
```
Your code is now on your repo on github!

Scenario 2: Creating your own repo

On github.com, create a new repo by clicking on the + button on the top right corner of the page.
[Skip this step if you've already created your folder, html file(s) and js file(s)] If you haven't, you can create your folder and files for your program:
```
mkdir my-awesome-repo
cd my-awesome-repo
touch index.html style.css script.js
```
In the terminal, cd to the folder which you want to push to github, and run:
```
git init
git remote add origin YOUR_GITHUB_REPO_URL
```
Your local repo is now linked to your github repo. To push your code to github, run the message commands as before:
```
git add -A
git commit -m "your awesome commit message"
git push -u origin master
```
Done! Remember to run step 4 (add, commit, push) regularly!

Javascript

Syntax of regularly used javascript stuff:

Loops

For loops:

for (var i = 0; i < array.length; i++) {
     // your code here
}

While loops:

var i = 0;
while (i < 5) {
     console.log("i is " + i);
     i++;
}

'For in' loops (for iterating through key-value pairs of an object):

var car = {
     wheels: 4,
     doors: 2,
     seats: 5
};
for (var thing in car) {
     console.log("my car has " + car[thing] + " " + thing);
}

Conditionals

If-else statement:

var isTasty
var food = "pizza"

if (food === "pizza") {
  isTasty = true;
} else if (food === "fried chicken") {
  isTasty = true
} else {
  isTasty = false;
}
console.log("Is the food tasty?", isTasty);

Functions

Defining functions:

function myAwesomeFunction() {
    // define your function here
}

Defining functions that take in one or more arguments:

function introduceMyself(name, age) {
  console.log('Hi! I am ' + name + ' and I am ' + age + ' years old.')
}

introduceMyself('Bob', 36)
// --> Hi! I am Bob and I am 36 years old.
