Frequently Asked Questions
Yes, absolutely. ToolZeno operates 100% client-side in your web browser. Your JavaScript, TypeScript, JSX, or TSX statements are processed locally in your browser's active memory and are never uploaded, sent, or saved to any backend servers.
A JavaScript Beautifier adds proper spacing, indentation, and structure to make the code highly legible for human developers. A JavaScript Minifier removes all whitespace, line breaks, comment blocks, and renames variables and parameters to shorter representations (mangling) to minimize network payload size and improve load times.
Standard minifiers like Terser only parse JavaScript. To minify TypeScript, the tool compiles and strips the type annotations (interfaces, types, generics) client-side using Sucrase first, and then compresses the resulting JavaScript using Terser.
Yes. The formatter is integrated with Prettier's Babel and TypeScript parsers, which fully support modern ESNext syntax, including React JSX and TSX templates. They are pretty-printed and aligned correctly.
Prettier is the industry-standard opinionated code formatter. It standardizes styling rules across development teams, reducing style debates and focusing commits on logic rather than formatting changes.
