GRATIS Preview Of JavaScript Beginner - Language Of The Web

This chapter is an introduction of mine. My motivation behind these courses. My experience so far and also my achievements. Ultimately, why my courses are different compared to any other course and why you can listen and trust my voice.

Explore that JavaScript is the language of the Web and that you should learn this language because the majority uses it. All web browsers include a JavaScript interpreter. To build Web Applications, you have to know the holy Triad of HTML & CSS & JavaScript.

I explain to you the history of JavaScript a.k.a ECMAScript in a brief overview. You will be bootstrapped for a little chit-chat with your colleagues and know whenever I speak of ES6, ECMAScript 3, or ECMAScript 5.

I also give you an overview of the distinct features in each version and which will be explained during this course and which in my JavaScript Advanced Course.

There are 2 parts of JavaScript, dependent on the field of application. 1. “client-side JavaScript” - Browser 2. „server-side JavaScript“ - Server

The JavaScript Core Functionality comprises: Lexical structure, Types, Values, Variables, Statements & Expressions & Operators, Objects & Arrays, Functions, Classes & Functions. You will understand what is Core JavaScript and why there is a difference to Client-Side JavaScript.

I show you a minor example of my DUC-Idle Game (www.ducidle.com) and explain to you the language concepts and what to accomplish in a minor example of the DUC-Idle Character Guessing Game. It has almost anything you will learn in this course. Everything would be too much, but after the course, you are going to bring this application to the next level with all the gathered knowledge from this course.

All we need is a simple program called Visual Studio Code and we will install and setup it together.

We need the Chrome Browser - for the client-side and for debugging - Version: 90.0.4430.93 (Official Build) (x86_64).

Then we set up the environment and create our first JavaScript program together.

The Lexical structure describes the elementary rules to write a program in a language. It is the lowest level of syntax. Determines how statements are separated and specifies variable names have to look alike. Object declaration and function definitions are also given by it and the way how you comment your code is also included.

Computer programs work by storing values into variables and manipulating values of these variables (containers).

The fundamental characteristic of a programming language is the set of types it supports.

When a program needs to retain a value for future use assigns the value to (or “stores” the value in) a variable.

JavaScript distinguishes between two basic types: Primitive and Object. You will take a closer look at the object type.

The Summary of this chapter is about the two basic types of JavaScript comprises
