1. Explanation About Interpreted And Compiled Programming Languages

Computers don't speak English or Spanish, they speak Machine Code. Machine code is a computer programming language comprising binary instructions which computers respond to directly, It's written in machine language. Therefore, a machine i.e., a computer, can execute it without any translation or conversion.

So then, How do computers read the code we write in a programming language? If we gave computers the text of the logic and instructions we want to execute with a set program, the computer wouldn't have a way to read it and execute it.

Introducing Interpreted and Compiled Programming Languages

A programming language allows us to translate the abstract 1 & 0's / Binary into something humans can understand.

Two types of languages

1. High-Level Ex: Java, Javascript, Python, C# and many more.

Upside: Easier for us to understand the syntax and write code.

Downside: It takes longer to translate into machine code.

2. Low-Level Languages that are closer to Machine Code therefore easier for the computer to read.

Benefits Include: They're fast, precise control on how they want the computer to function.

Ex: Machine code, Assembly Language

We need to get our Source Code converted into Machine code somehow before it can run: There are two ways to turn Source code into machine code and it's up to the language you're using Compiled or Interpreted language.

1. Compiled: Source Code Compiler Program : Translates Source Code into Machine Code and makes it an Executable file (Machine Code) Separate Executable file on Machine Code Executable File

2. Interpreted Source Code Interpreter Program (turns it into machine code on the fly, line by line, on the spot) Processes on the spot (Not saved as a another file) Ex: Javascript interpreted into the web browser

Compiled

Pros	Cons
ready to to run	not cross platform
often faster	inflexible
source code is private	extra Step

Interpreted

Pros	Cons
cross-Platform	interpreter required
simpler to test	inflexible
easier to debug	source code is public

Compiled: C, C++, Objective-C Interpreted: PHP, JavaScript Hybrid: Java, C#, VB.Net, Python

Intermidiate Approach: Takes it as far as it can into Machine Code, often Assembly and let's the other party finish the rest.
JIT: Just in time compilation.

2. Is Java compiled or interpreted, or both?

Java is an Intermidiate Hybrid approach where it's neither compiled or interpreted all at one time, it's done half and half, we compile one part of the way to what's called an intermidiate language which takes it as far as long to machine code as it can get while still being portable across platforms, you then distribute the Intermidiate Language File sending it to the people who need to run it and each person who runs it takes it to the last step to take it to machine code. JIT Compilation / Bite Code.

3. Pseudocode currency converter

1. START
2. BTC <--- GET FROM ('https://www.coinbase.com/price/bitcoin')
3. USD <--- GET
4. BTC2USD <--- BTC * USD
5. Print BTC2USD
6. END

Feedback on the Videos and Re-search

Summary

The Weird History of Java

It was really interesting video to watch, gave me a perspective on how javascript has evolved over the las two decades and a half since it's release in Dec '95 Brendon Ike's, being banned by MS in the Internet Explorer, Ecma Standarizing JS, touch on the Tech Bubble of march 2000s, Jquery, sep 8 Chrome V8engine, May 2009 Node Js "Launch Web applications at scale", ES 3.1 == ES5, ES5 introduced (JSON SUPPORT, Functional array and object methods, stric mode, accessors many other), Single Page application frameworks Oct 2010: Backbone & Angular, similar problem different approaches. backbone was light weight Dom updates with imperative programming style, Angular Js more inclusive and use declarative programming, 2015 React Js included angular js with declarative UI but improve them with uni-directional data flow immutability and use of the virtual DOM. The creator of the video is Bullish on javascript, and has learned to always bet on javascript.
