jsfmt is a command-line tool and Node.js library for formatting, searching, and rewriting JavaScript, analogous to Go's gofmt. It operates on the AST via esprima and esformatter, supporting pattern-based search and rewrite rules like '_.reduce(a, b, c) -> a.reduce(b, c)'.

Use cases

• format javascript files like gofmt
• find all console.log calls in a project
• rewrite underscore.js calls to native methods
• check which files need formatting
• refactor api changes across a codebase
• output javascript as a ast

When to choose

• you want gofmt-style formatting for javascript
• you need AST-based search or bulk rewriting of code patterns
• you want a scriptable codemod tool with a simple pattern syntax

When to avoid

• you need a modern, actively maintained formatter like prettier
• you need ES6+ or JSX support
• you want IDE-integrated formatting
