• To "declassify" and quote a substitution value used in a details`...` template literal, enclose that substitution expression in a call to quote. This makes the value appear quoted (as if with JSON.stringify) in the message of the thrown error. The payload itself is still passed unquoted to the console as it would be without quote.

    Parameters

    • payload: any

      What to declassify

    • Optional spaces: string | number

    Returns StringablePayload

    The declassified payload

    Example

    For example, the following will reveal the expected sky color, but not the actual incorrect sky color, in the thrown error's message:

    sky.color === expectedColor || Fail`${sky.color} should be ${quote(expectedColor)}`;
    

    Example

    The normal convention is to locally rename details to X and quote to q like const { details: X, quote: q } = assert;, so the above example would then be

    sky.color === expectedColor || Fail`${sky.color} should be ${q(expectedColor)}`;
