The number of cited reserved words including keywords is 50–60 and varies depending on the implementation. The following features are common to all conforming ECMAScript implementations unless explicitly specified otherwise. This is called the event loop, described as “run to completion” because each message is fully processed before the next message is considered.
This set of articles provides a comfortable starting point to help you begin learning frameworks. This module focuses on the essentials of the core JavaScript language, plus some key surrounding topics — learning these topics will give you a solid basis to work from. This means that cases where some proposals for new ECMAScript features have already been implemented in browsers, documentation and examples in MDN articles may use some of those new features. W3Schools maintains a complete JavaScript reference, including all HTML and browser objects.

- For this JavaScript tutorial, it is assumed that the reader has prior knowledge of HTML coding.
You might also hear the terms server-side and client-side code, especially in the context of web development. There are advantages to both types of language, but we won’t discuss them right now. However, JavaScript is still considered an interpreted language, since the compilation is handled at run time, rather than ahead of time. This means that the button object has not been initialized yet, so we can’t add an event listener to it.

There was a desire in the flourishing web development scene to remove this limitation, so in 1995, Netscape decided to add a programming language to Navigator. The ECMAScript standard does not include any input/output (I/O), such as networking, storage, or graphics facilities. It has dynamic typing, prototype-based object-orientation, and first-class functions. JavaScript is a high-level, often just-in-time–compiled language that conforms to the ECMAScript standard. These engines are also utilized in some servers and a variety of apps.
