Sucrase vs UglifyJS
Both stand on javascript build tools. Which one you can start free with, which one lets you read the code, and what each costs once you pay.
Choose Sucrase for development builds targeting modern JavaScript runtimes when its available transforms and integrations fit your project. Look elsewhere if you need type checking, old-browser output, extensible plugins, or a production-build tool better suited to that role.
Visit SucraseChoose UglifyJS if you need a free JavaScript toolkit with command-line and API options, source maps and AST utilities. Look elsewhere if your syntax needs exceed its supported features without transpilation, or if you need the defaults to target the compatibility environments it excludes.
