Frequently asked questions

Why convert ES6 to ES5?

ES5 runs on older browsers like IE11. Converting ES6 features to ES5 ensures your code works on legacy browsers that don't support modern syntax.

What ES6 features are converted?

Arrow functions, template literals, const/let to var, destructuring, and spread operators are converted to ES5-compatible equivalents.

Should I use this instead of Babel?

This is a simple converter for small snippets. For production, use Babel or TypeScript which handle more features and edge cases.
