Week 2 - Session 1 - JavaScript Fundamentals

A JavaScript program is essentially a list of instructions for the computer to follow in order to achieve whatever useful thing the program is required to do. Each instruction in a program is called a statement. In JavaScript, statements are composed of values, operators, expressions and keywords, and end with a semicolon.

 Values: there are two types of values in JavaScript, literal values (Numbers, Strings, Booleans, Arrays, Objects), and variable values (var, const, and let).

 Operators: these are special symbols that are used to combine two values and create a new one. Arithmetic, String, Logical, Comparison, and Assignment operators.

 Expressions: an expression is a combination of literal values, variables, and operators, which evaluates to a single value.

 Keywords: these are basically reserved words that perform special actions and cannot be used as variable names.

 JavaScript statements can be grouped together in blocks using curly braces ({}). Blocks are normally found in functions, if-statements, and loops.

My experience with  @MCRcodes   as a Quality Assurance Tester.  This is an evening part-time coding boot camp based in central Manchester which runs for 24 weeks, from February 2018 to July 2018. Week 9 (April 2018) - After spending two decades using the internet, I finally have an understanding how it works now, and the communication between the server and the client. Nice to create and run a simple server using Express and I now know what API actually means now, I think. Really appreciate how amazing and powerful the npm  package manager really  is, and looking forward to installing other future packages.  We have now started our back-end programming journey. Session 1 -  The Internet, the Web, HTTP Session 2 -  Web APIs & Express Week 10 - Really enjoying creating and reading test units for server assignments. Additionally, learning s ynchronous/a synchronous programming has been a tease.   Unfortunately, I was unable to attempt few classes due to unplanned c

Week 9 - Session 1 - The Internet, the Web, HTTP

blog image source The internet, a worldwide network of computer networks, a llows transfer of information between networks, and the information is transferred using the internet protocol suite (IP/TCP). One of the most commonly used services on the internet is the world wide web (www). A primary mode of transferring data (resources) over the internet for billions. The application protocol that makes the web work is hypertext transfer protocol. blog image source As web developers, we are mainly interested in HTTP,  a protocol that web browsers and web servers use to communicate with each other over the Internet.  The Hypertext Transfer Protocol (HTTP) is designed to enable communications between clients and servers. HTTP works as a request-response protocol between a client and server. A web browser may be the client, and an application on a computer that hosts a website may be the server.
