This is irrespective of where someone defines the function or variables. We can understand thisvariable by knowing how, when and from an instance calls the function or variable. Execution context means here means the manner of calling of functions. Every JavaScript function has a reference to its current execution context while executing, called this. In JavaScript, “ this” variable is a variable that every execution context gets, in a regular function call. this keyword defines an object, that object which is executing the current bit of JavaScript code. If you enroll now, you’ll get the third part and any other courses I add to this bundle for free.Understanding of thisvariable in JavaScript requires very basic knowledge of JavaScript. The bundle is currently on sale for $29 and contains the first two parts. You can get these courses individually or as part of my Ultimate Java Mastery series bundle. In this part, I’m planning to talk about the module system, JDBC, generics, streams, JDBC, concurrency, etc. Ultimate Java Mastery Part 3 is about advanced topics in Java and is not produced yet. Every single minute of the course is worth watching. This is also a short and sweet course (4 hours long) that you can watch in an afternoon. Most books and courses fail to explain object-oriented programming! I promise that you’re not going to find this content anywhere else. Even if you do have a job, I’d still encourage you to watch this course because it will change how you think about building software. This course is a must for anyone pursuing a job as a professional software engineer. That’s why it took me personally a long time to understand what object-oriented programming is really all about. There are tons of bad and wrong information about object-oriented programming out there. Ultimate Java Mastery Part 2 is about object-oriented programming in Java. Also, there is not a global definition of what is a “better” language. Marketing! It’s got nothing to do with which language is better. To be fair, C# is more feature-rich than Java. You’ll probably miss some of your favorite C# features. If you’re a C# developer, you can go through the course quickly and get familiar with Java syntax. It teaches you the fundamentals of programming in Java. Ultimate Java Mastery Part 1 is a short and sweet course (3.5 hours) that you can watch in an afternoon. No, let’s see what these Java courses are all about. So, the bottom line is: Java has a big job market and it’s not going anywhere anytime soon. Once you learn Java, you can quickly pick up Kotlin. If you want to learn Kotlin, you still need to know Java, otherwise, you’ll get stuck along the way. That’s why it’s hard (and sometimes impossible) to convince businesses to invest in re-writing their applications.Īlso, most of Android ecosystem is based on Java. Wrong! In most cases, the cost of doing so outweighs the benefits. There’s actually no reason to do so.Ī common misconception amongst developers is that just because there’s a new language or framework, an existing application should be re-written with that new language/framework. These are not going to be overwritten with Kotlin over the night. There are millions of apps and websites already built with Java. But that does not mean that Java is dead! What about Kotlin? In case you don’t know, Kotlin is a new language and it’s the preferred language for building new Android apps. Java is a versatile programming language and you can use it to build all kinds of applications from stand-alone desktop applications to complex, distributed applications. It’s also the language behind millions of Android apps. So, that changed the priority of the courses in my pipeline. įirst and foremost, I had tons of requests for a Java course amongst my students. You might ask why I’ve been working on Java courses. I’m super excited to let you know that I just added two new Java courses to my coding school. July 17th, 2019 Comments The Ultimate Java Series is here!
