Engine262 - How to "RUN" the ecmascript specification? | Javascript engine
If you have tried reading the Ecmascript specification (javascript), a common problem is that you can't really run or debug parts of the specification to see how it works. So, you can run the code in a simple js engine like Engine262.
Using engine262, we will debug why `[ ] == ![ ]` evaluates to true.

Attacking ECMAScript Engines With Redefinition
by Natalie Silvanovich
The dynamic nature of ECMAScript allows for functions and properties to be redefined in a variety of ways - even functions that are vital for internal functionality of the ECMAScript engine. This presentation explores the problems that can arise from ECMAScript redefinition. It goes through the various ways that functions and properties can be redefined in different ECMAScript implementations and describes several vulnerabilities we found as a result of these methods. It also provides some strategies for finding these types of security issues in other targets.

Understanding the Difference Between JavaScript and ECMAScript
If you've been delving into the world of web development, you’ve likely come across the terms JavaScript and ECMAScript. While they are often used interchangeably, understanding the distinction between them is crucial for any developer. This guide aims to shed light on their relationship, their differences, and their importance in programming.
What is JavaScript?
JavaScript is a high-level, interpreted programming language known for making webpages interactive. Developed by Netscape in 1995, JavaScript was initially named Mocha, then LiveScript, and eventually renamed JavaScript. Despite the naming confusion, it is not directly related to Java and runs in web browsers to enhance user experience by enabling dynamic content.
JavaScript is versatile, supporting object-oriented, imperative, and functional programming styles. It plays a vital role in front-end development but can also be used on the server side through environments like Node.js.
What is ECMAScript?
ECMAScript (ES), on the other hand, is a standardized scripting language specification created by ECMA International. The purpose of ECMAScript is to ensure the interoperability of web pages across different web browsers.
ECMA International developed the first edition of ECMAScript in 1997, and since then, several editions have been released, with notable versions being ES5, ES6 (also known as ECMAScript 2015), and later editions.
The key point to note is that ECMAScript is a specification, not a programming language. JavaScript is an implementation of that specification, along with other implementations like JScript and ActionScript.
Key Differences and Relationship
Nature and Role:
JavaScript: An actual programming language used to develop interactive and dynamic web content.
ECMAScript: A standard specification that defines how a scripting language should be implemented.
Development and Updates:
JavaScript is updated and maintained by various parties, including browser vendors, to align with the latest ECMAScript standards.
ECMAScript is updated by TC39 (Technical Committee 39) at Ecma International, aiming to define clear specifications and guidelines for scripting languages.
Usage Context:
JavaScript: Utilized directly by developers in their code written for web applications, web services, and more.
ECMAScript: Refers to the standard that developers reference to understand what features and functionalities should be available in a compliant scripting language.
Versioning:
JavaScript: Doesn't have its own versioning separate from ECMAScript. It adopts the versions of ECMAScript (e.g., ES6 features are available in corresponding JavaScript versions).
ECMAScript: Has specific versions like ES5, ES6, ES7, and so on.
Why Understanding This Matters?
Understanding the difference between JavaScript and ECMAScript helps developers comprehend updates and features of the language more precisely. When a new version of ECMAScript is released, it includes new features and enhancements that JavaScript engines subsequently implement, impacting how developers write code.
Staying informed about ECMAScript versions assists developers in utilizing the most modern and efficient features available in JavaScript, ensuring better performance, coding efficiency, and cross-browser compatibility.
In conclusion, while JavaScript and ECMAScript are closely related, they serve different purposes within the ecosystem of web development. JavaScript is the practical tool developers use, whereas ECMAScript is the standard ensuring its coherent implementation across various platforms and browsers.

SUMMARY
=======
An ECMAScript engine is a program that executes source code written in a version of the ECMAScript language standard, for example, JavaScript.
These are new generation ECMAScript engines for web browsers, all implementing just-in-time compilation (JIT) or variations of that idea. The performance benefits for just-in-time compilation make it much more suitable for web applications written in JavaScript.
Carakan: A JavaScript engine developed by Opera Software ASA, included in the 10.50 release of the Opera web browser, until switching to V8 with Opera 15 (released in 2013).
Chakra (JScript9): A JScript engine used in Internet Explorer. It was first previewed at MIX 10 as part of the Internet Explorer 9 Platform Preview.
Chakra: A JavaScript engine used in Microsoft Edge.
SpiderMonkey: A JavaScript engine in Mozilla Gecko applications, including Firefox. The engine currently includes the IonMonkey compiler and OdinMonkey optimization module, has previously included the TraceMonkey compiler (first javascript JIT) and JägerMonkey.
JavaScriptCore: A JavaScript interpreter and JIT originally derived from KJS. It is used in the WebKit project and applications such as Safari. Also known as Nitro, SquirrelFish and SquirrelFish Extreme.
Tamarin: An ActionScript and ECMAScript engine used in Adobe Flash.
V8: A JavaScript engine used in Google Chrome, Node.js, and V8.NET.
Nashorn: A JavaScript engine used in Oracle Java Development Kit (JDK) since version 8.
iv, ECMAScript Lexer / Parser / Interpreter / VM / method JIT written in C++
CL-JavaScript: Can compile JavaScript to machine language on Common Lisp implementations that compile to machine languageThe following engines use runtime interpreters, which do not compile into native machine code and generally run more slowly:
Continuum: A self-interpreter that supports older drafts of the ECMAScript 2015 specification. Uniquely, the engine is implemented in ECMAScript 3, which made it possible to run ES2015 in browsers as old as IE6.
Futhark: The ECMAScript engine of the Opera web browser versions 9.50 to 10.10.
InScript: An obsolete proprietary library used for iCab 2 and 3.
JScript: The engine that is used in Internet Explorer for versions up to IE9, and one component of the Trident layout engine.
KJS: The engine used in Konqueror, and one component of KHTML, a predecessor to JavaScriptCore.
Linear B: The ECMAScript engine of the Opera web browser versions 7.0 to 9.50, exclusive.
Narcissus: JavaScript implemented in JavaScript (a meta-circular evaluator), intended to run in another JavaScript engine, of theoretical and educational nature only.
JS-Interpreter A lightweight JavaScript interpreter implemented in JavaScript with step-by-step execution.
QtScript: Originally developed by Trolltech, now owned by The Qt Company. It provides QObject integration with JavaScriptCore.
Rhino: One of several JavaScript engines from Mozilla, using the Java platform.
YAJI: An ECMAScript engine based on the FESI implementation by Jean-Marc Lugrin in 1999, using the Java platform, currently being developed to support the latest standards (ECMAScript spec. 262, v5.1).
Duktape: A small footprint, easily embeddable Ecmascript E5/E5.1 engine.
The Kinoma Platform, an ECMAScript 6 runtime environment and framework. This is one of the first runtimes to correctly implement almost all of the ECMAScript 6 specification, currently unmaintained.
Moddable successor of Kinoma Platform, currently active project and aims to support more recent versions of ECMAScript.
Jsish: A JavaScript interpreter with builtin SQLite, JSON, WebSocket, and ZVFS support.
Websocket.js: An embeddable Javascript engine with HTTP/Websocket support.

SUMMARY
=======
An ECMAScript engine is a program that executes source code written in a version of the ECMAScript language standard, for example, JavaScript.
These are new generation ECMAScript engines for web browsers, all implementing just-in-time compilation (JIT) or variations of that idea. The performance benefits for just-in-time compilation make it much more suitable for web applications written in JavaScript.
Carakan: A JavaScript engine developed by Opera Software ASA, included in the 10.50 release of the Opera web browser, until switching to V8 with Opera 15 (released in 2013).
Chakra (JScript9): A JScript engine used in Internet Explorer. It was first previewed at MIX 10 as part of the Internet Explorer 9 Platform Preview.
Chakra: A JavaScript engine used in Microsoft Edge.
SpiderMonkey: A JavaScript engine in Mozilla Gecko applications, including Firefox. The engine currently includes the IonMonkey compiler and OdinMonkey optimization module, has previously included the TraceMonkey compiler (first javascript JIT) and JägerMonkey.
JavaScriptCore: A JavaScript interpreter and JIT originally derived from KJS. It is used in the WebKit project and applications such as Safari. Also known as Nitro, SquirrelFish and SquirrelFish Extreme.
Tamarin: An ActionScript and ECMAScript engine used in Adobe Flash.
V8: A JavaScript engine used in Google Chrome, Node.js, and V8.NET.
Nashorn: A JavaScript engine used in Oracle Java Development Kit (JDK) since version 8.
iv, ECMAScript Lexer / Parser / Interpreter / VM / method JIT written in C++
CL-JavaScript: Can compile JavaScript to machine language on Common Lisp implementations that compile to machine languageThe following engines use runtime interpreters, which do not compile into native machine code and generally run more slowly:
Continuum: A self-interpreter that supports older drafts of the ECMAScript 2015 specification. Uniquely, the engine is implemented in ECMAScript 3, which made it possible to run ES2015 in browsers as old as IE6.
Futhark: The ECMAScript engine of the Opera web browser versions 9.50 to 10.10.
InScript: An obsolete proprietary library used for iCab 2 and 3.
JScript: The engine that is used in Internet Explorer for versions up to IE9, and one component of the Trident layout engine.
KJS: The engine used in Konqueror, and one component of KHTML, a predecessor to JavaScriptCore.
Linear B: The ECMAScript engine of the Opera web browser versions 7.0 to 9.50, exclusive.
Narcissus: JavaScript implemented in JavaScript (a meta-circular evaluator), intended to run in another JavaScript engine, of theoretical and educational nature only.
JS-Interpreter A lightweight JavaScript interpreter implemented in JavaScript with step-by-step execution.
QtScript: Originally developed by Trolltech, now owned by The Qt Company. It provides QObject integration with JavaScriptCore.
Rhino: One of several JavaScript engines from Mozilla, using the Java platform.
YAJI: An ECMAScript engine based on the FESI implementation by Jean-Marc Lugrin in 1999, using the Java platform, currently being developed to support the latest standards (ECMAScript spec. 262, v5.1).
Duktape: A small footprint, easily embeddable Ecmascript E5/E5.1 engine.
The Kinoma Platform, an ECMAScript 6 runtime environment and framework. This is one of the first runtimes to correctly implement almost all of the ECMAScript 6 specification, currently unmaintained.
Moddable successor of Kinoma Platform, currently active project and aims to support more recent versions of ECMAScript.
Jsish: A JavaScript interpreter with builtin SQLite, JSON, WebSocket, and ZVFS support.
Websocket.js: An embeddable Javascript engine with HTTP/Websocket support.
