ECMAScript
Status, process, and documents for ECMA-262
...It is the twelfth edition of the ECMAScript Language Specification. Since publication of the first edition in 1997, ECMAScript has grown to be one of the world's most widely used general-purpose programming languages. It is best known as the language embedded in web browsers but has also been widely adopted for server and embedded applications. ECMAScript is based on several originating technologies, the most well-known being JavaScript (Netscape) and JScript (Microsoft). ... -

bignumber.js
A JavaScript library for arbitrary-precision decimal arithmetic
...Includes a toFraction and a correctly-rounded squareRoot method. Supports cryptographically secure pseudo-random number generation. Wide platform compatibility, uses JavaScript 1.5 (ECMAScript 3) features only. If a smaller and simpler library is required see big.js. It's less than half the size but only works with decimal numbers and only has half the methods. It also has fewer configuration options than this library, and does not allow NaN or Infinity. See also decimal.js, which among other things adds support for non-integer powers, and performs all operations to a specified number of significant digits. -

FormatJS
The monorepo home to all of the FormatJS related libraries
...It includes a set of core libraries that build on the JavaScript Intl built-ins and industry-wide i18n standards, plus a set of integrations for common template and component libraries. For most web projects, internationalization happens in the template or view layer, so we've built integrations with React & Vue. FormatJS is aligned with: ECMAScript Internationalization API (ECMA-402), Unicode CLDR, and ICU Message syntax. By building on these industry standards, FormatJS leverages APIs in modern browsers and works with the message syntax used by professional translators. FormatJS has been tested in all the major browsers (IE11, Chrome, FF & Safari) on both desktop and mobile devices. -

MicroQuickJS
Public repository of the Micro QuickJS Javascript Engine
...The engine is intentionally small in ROM footprint while still providing practical performance comparable to lightweight desktop-grade embeddable engines in its class. To stay small and predictable, it supports a subset of JavaScript close to ES5 rather than modern ECMAScript features, which keeps implementation complexity and runtime overhead lower. It also offers a stricter mode that forbids certain error-prone or inefficient constructs, encouraging safer and more deterministic code in embedded environments. -

babel-eslint
A wrapper for Babel's parser used for ESLint
babel-eslint allows you to lint ALL valid Babel code with the fantastic ESLint. ESLint's default parser and core rules only support the latest final ECMAScript standard and do not support experimental (such as new features) and non-standard (such as Flow or TypeScript types) syntax provided by Babel. babel-eslint is a parser that allows ESLint to run on source code that is transformed by Babel. You only need to use babel-eslint if you are using Babel to transform your code. If this is not the case, please use the relevant parser for your chosen flavor of ECMAScript (note that the default parser supports all non-experimental syntax as well as JSX). ... -
