Homework #3

Instructions

---

1. Feynman Writing Prompts - Write out explanations of the following concepts like you are explaining it to a 12 year old. Doing this will help you quickly discover any holes in your understanding. Ask your questions on Slack.

• Objects: A phone is an object in real life, and it has properties like color, size, and type. An object is also the same thing. This code gives a simple value to an object, and with in curly braces you can add more details like what color is the object?

• Properties: Furthering my example from Objects, a property is the color of your phone. A property has a key and a value. The key in this example would be color, and the the value would be what ever color your phone is.

• Methods: Objects can also have methods. With the phone example a method for the phone could be turning on. A function could be written within the object that would turn the phone on. A method that we use frequently is ‘console.log()’. There is an object called console, and a method attached to it called log. Calling this method allows us to print what ever is in the parentheses.

• for in loop: Allows the developer to iterate over properties in an object that have values. It’s similar to the ‘for’ loop practiced in lesson two, but specific for objects.

• Dot notation vs bracket notation:

2. Fork and clone this repo. When you need to commit use the following commands.

   • git status
   • git add --all
   • git status
   • git commit -m "your commit message"
   • git push origin master

3. Install dependencies using npm install. Run tests using npm test.

4. Make the tests pass!

Congratulations on finishing Homework #3!
