JavaScript Programming from Scratch to Guru 2.0

<p>JavaScript is currently the most popular and most popular programming language in the world. And it&#39;s worth noting that its popularity has skyrocketed in recent years, and its scope has expanded considerably. When I wrote my first JavaScript course a few years ago (called &quot;JavaScript, jQuery and Ajax from Zero to Guru&quot;), the actual scope of this language was limited to Web pages. Now JavaScript is used in many different areas, which means that any self-respecting programmer must know it.</p> <p>1. Introduction</p> <p>In this section you will learn:</p> <p>How to get through the course with maximum efficiency?</p> <p>How does JavaScript work? This is very important basic information to know.</p> <p>What software will you need to write JavaScript programs, where to download it, and how to install it?</p> <p>After watching this section you will already know how JavaScript works, and you will have all the necessary software to write your own programs in this language.</p> <p>2- JavaScript Programming Basics</p> <p>Now that we have everything ready to start, we can start writing our first JavaScript programs. And in this section you will learn:</p> <p>How to write JavaScript programs?</p> <p>How to work with the developer console?</p> <p>What are variables, what types of variables are there, how are they used?</p> <p>How is the conversion from one type to another?</p> <p>What are constants and when should they be used in practice?</p> <p>What are the arithmetic, logical and string operations? All of these are provided with many examples.</p> <p>What is the conditional operator for and what does it look like?</p> <p>How do the for and while loop operators work and what are they for?</p> <p>How to use the switch-case operator?</p> <p>What are functions and how to use them correctly in JavaScript?</p> <p>What are function expressions?</p> <p>What are arrow functions?</p> <p>How to handle errors with try-catch and what are exceptions?</p> <p>What are arrays and how to work with them in JavaScript?</p> <p>What is a closure? This, according to my observations, is one of the most popular interview questions for JavaScript developers (and not only for them, by the way). In the course you will learn the answer to this question in detail.</p> <p>How to connect third-party scripts?</p> <p>As a practical example, we will create a simple data warehouse, for which we will request data from the user. You will also see how various commands from the user are analyzed and processed.</p> <p>This is a rather lengthy section, which will give you all the necessary foundation for creating your first useful programs in JavaScript.</p> <p>3. object-oriented programming in JavaScript</p> <p>Object-oriented programming (OOP) is the most popular and most common approach to program development. Theoretically, any program can be made without it, but practically for medium and large projects it will be extremely difficult and very long. Moreover, there are a lot of built-in objects in JavaScript, and you need to know how to work with them. That&#39;s why you need to know OOP. And just in this section you will learn:</p> <p>What is OOP?</p> <p>What are the OOP paradigms?</p> <p>How objects are created in JavaScript and how to work with them?</p> <p>How to create constructors and methods?</p> <p>What is Symbol and how to use it?</p> <p>What are toString and valueOf methods?</p> <p>What is a class and how is it created in JavaScript?</p> <p>What are getters and setters in JavaScript?</p> <p>What are static properties and methods and, most importantly, how to use them in practice?</p> <p>How is class inheritance implemented in JavaScript and, most importantly, how to use this paradigm in real projects?</p> <p>What are access modifiers?</p> <p>What are property flags and how to use them?</p> <p>What are impurities?</p> <p>As a practical example, we will create a simple data warehouse, the data for which we will request from the user. You will also see how various commands from the user are analyzed and processed.</p> <p>This is a rather lengthy section, which will give you all the necessary foundation for creating your first useful programs in JavaScript.</p> <p>Object-oriented programming in JavaScript</p> <p>Object-oriented programming (OOP) is the most popular and most common approach to program development.
