Notes

let and const

• mutable data type value examples:
  • strings, null, numbers, undefined, booleans
• immutable examples:
  • object literals
  • arrays
• Pass by Reference vs Pass by Value
  • reference passes a pointer
  • problems could be subtle ```javascript let person.name = ‘Paul’; let person.age=21;

  let person2 = person; person2.name = ‘Not Paul’;

  console.log(person); // surprising results.

  ```

Redirect:

• Let’s say you’re talking to our sister and she wants to borrow Great Grandma’s silver water jug or something. But you don’t have it - Mom has it. So you tell our sister to get it from Mom instead. This happens all the time in real life and it happens all the time when machines start talking too. On the internet, it’s called a “redirect”.

How does this article inform your approach to working with others moving forward? it reminds me to be cognizant that we’re all approaching each situation slightly differently.

How I explained REST to my brother

1. Who is Roy Fielding?

   He helped write the first web servers, that sent documents across the internet… and then he did a ton of research explaining why the web works the way it does. His name is on the specification for the protocol that is used to get pages from servers to your browser.

2. Why don’t the techniques that we use in this class work well when we need to be able to talk to all of the machines in the world?

   there is no universally agreed upon noun by computers. There’s a ton of nouns (laptop, coffee, book, etc); but there are a few number of verbs that can be applied to them. GET, POST, PUT, PATCH are the verbs of computers.

3. What is the HTTP protocol that Fielding and his friends created?

   When Fielding and his colleagues started building the web, being able to talk to any machine anywhere in the world was a primary concern. HTTP does this, by use of URL’s HTTP is actually a general purpose protocol for applying verbs to nouns

4. What does a GET do?

   when you go to a web page, the browser does an HTTP GET on the URL you typed in and back comes a web page You can also GETmusic, video, data, etc.

5. What does a POST do?

   If one system needs to add something to another system, it would use an HTTP verb of POST

6. What does PUT do?

   If a system wants to replace something in another system, it uses an HTTP verb of PUT

7. What does PATCH do?

   If a system wants to do a partial update to another system, it uses an HTTP verb of PATCH
