Frequently Asked Questions
Is this formatter free to use?
Yes, our JavaScript formatter is completely free to use with no limitations. We also offer an API for programmatic access for developers who need to integrate formatting capabilities.
Is my code secure when using this formatter?
Absolutely. Your code is processed entirely in your browser and is never sent to our servers. This ensures complete privacy and security for your code. You can format sensitive or proprietary code without concerns.
Can I customize the formatting style?
Yes, you can adjust several formatting options including indent size and whether to use tabs or spaces. For some languages, additional formatting options are available to suit your specific style preferences.
Does the formatter validate my code?
Yes, our formatter includes basic validation capabilities that check for syntax errors and structural issues in your JavaScript code. Any identified issues will be highlighted to help you correct them.
Does the JavaScript formatter support modern ES6+ syntax?
Yes, our JavaScript formatter fully supports modern ES6+ syntax including arrow functions, destructuring, classes, template literals, async/await, and other newer JavaScript features. It formats these constructs according to best practices.
Will the formatter add or remove semicolons in my JavaScript?
Our formatter preserves your existing semicolon usage. If your code uses semicolons, they will remain in place. If your code omits semicolons (ASI style), the formatter will respect that choice. The formatter focuses on spacing, indentation, and line breaks rather than enforcing semicolon style.
Can I use this formatter in my development workflow?
Yes, you can integrate this formatter into your development workflow. Many developers use it during code reviews, before committing code, or when working with legacy code. For more frequent use, consider setting up a similar formatter in your IDE or version control hooks.
What browsers are supported?
Our formatter works with all modern browsers including Chrome, Firefox, Safari, and Edge. We recommend using the latest version of your preferred browser for the best performance, especially when formatting larger files.
