Frequently Asked Questions
How does the JavaScript formatter work?▼
It adds line breaks after semicolons and braces, indents code blocks, and preserves comments and strings. The formatter handles basic structures like functions, loops, conditionals, and object literals.
What kind of errors can it detect?▼
The formatter checks for unmatched braces {}, parentheses (), and brackets []. It tracks string literals, template literals, and comments to avoid false positives.
Does it support all JavaScript syntax?▼
The formatter handles common JavaScript patterns. For advanced formatting features like async/await, class syntax, and arrow functions, a dedicated tool like Prettier is recommended for production use.
