Keeping usage and formats tied to the receiving system
Whitespace formatting is conservative and preserves quoted text and regex spans. It is not a JavaScript, CSS or HTML grammar validator. A technical estimate needs the billable unit or output format the receiving system expects. Requests, tokens, storage and transfer can have separate rates. A text transformation should preserve meaningful characters rather than promise validation it does not perform.
Scope of this operation
The function operates on the supplied source and listed assumptions. Confirm the output format fits the receiving workflow before copying it into a production record. The example output for javascript formatter is shown below so the supplied source can be checked against the actual format. It is not evidence that the operation has run against your own file or account.
How it works
Insert indentation and line breaks around braces and semicolons while retaining recognized strings and comments.
Inputs
| Field | Example | Definition |
