The Easiest Way To Learn & Practice Modern Javascript
It’s outside the scope of this article—as a light introduction to JavaScript—to present the details of how the core JavaScript language is different from the tools listed above. You can learn more in MDN’s JavaScript learning area, as well as in other parts of MDN. Third-party frameworks and libraries that you can apply to HTML to accelerate the work of building sites and applications. Apply() has a sister function named call, which again lets you set this but takes an expanded argument list as opposed to an array. When we call fullName() alone, without using s.fullName(), this is bound to the global object. Since there are no global variables called first or last we get undefined for each one.
Static Properties – show you how to define static properties shared by all instances of a class. Computed property – explain the computed property and its practical application.

If you’re curious, createElement() is described in more detail in the API reference, but we won’t be using it in this tutorial. Don’t delete the entire src folder, just the original source files inside it. We’ll replace the default source files with examples for this project in the next step. The TypeScript Tutorial website helps you master Typescript quickly via the practical examples and projects.
The syntax of JavaScript not suited for everyone as different project demands different features. However, some modern tools like a Coffee script, Typescript, and Dart allowing developers to code in another language and then auto-convert into the JavaScript code. Here, JavaScript engine applies optimizations at each step of the process. It reads a compiled script and analyzes the data that passes in JavaScript engine. After that, it applies optimizations to the machine code from that acquired knowledge. When this process is completed, scripts run quite fast. This is an absolute JavaScript beginner guide to learn JavaScript with examples.
