Otto is a Go implementation of a JavaScript interpreter and embedded scripting engine. It provides a runtime environment for executing JavaScript code within native applications and includes a parser that converts source code into an abstract syntax tree for analysis and processing. The project enables the creation of custom scripting interfaces by binding native Go functions into the JavaScript global scope. It also includes a utility to translate JavaScript regular expression patterns into compatible formats for other programming languages. The engine supports safe script sandboxing throug

Goja is a JavaScript engine and ECMAScript compliant interpreter implemented entirely in Go. It serves as an embedded scripting engine that allows Go applications to execute JavaScript code and integrate a programmable scripting layer without relying on Cgo or external native dependencies. The project functions as a bridge between Go and JavaScript, enabling bidirectional data exchange and function invocation. It allows Go hosts to expose native structs, slices, and maps as JavaScript objects and arrays, while providing mechanisms to export script values and functions back into native Go type

Acorn is a JavaScript parser that converts source text into a structured abstract syntax tree. It follows the ESTree specification to produce a standardized JSON tree format, enabling consistent analysis of code structure and language versions. The project features a plugin-based grammar extension system that allows the base parser to be extended with custom rules for experimental or non-standard language features. It also includes syntax error recovery, which inserts placeholder nodes into the tree when encountering invalid code to allow parsing to continue. The toolset covers static analys

JSHint is a JavaScript static analysis tool and linter designed to detect errors and enforce coding standards. It functions as a syntax validator that scans source code to identify potential logic problems and programming mistakes before the code is executed. The tool provides a command line interface for analyzing files and directories. It supports the export of analysis results into standardized formats such as Checkstyle for integration with external build tools. Analysis is managed through a system of linting rule management and environment global configuration. This includes the ability
