Methods

  • Returns a new document path instance with the passed in key-path or index appended.

    A key-path can be a single property name or multiple property names separated by a dot. Indexes can also be specified as part of the key path using square brackets syntax. The empty string returns a document path representing the same portion of the document as the receiver. If a key path starts with a property name and is prefixed by a dot, the dot is ignored.

    Examples:

    • documentPath.at('mileage')
    • documentPath.at('driver.name')
    • documentPath.at('passengers[2]')
    • documentPath.at('passengers[2].belongings[1].kind')
    • documentPath.at('.mileage')

    Parameters

    • keyPathOrIndex: string | number

    Returns DocumentPath
