    Returns any

• forEach: function

  • forEach(
        children: Iterable<any, any, any>,
        fn: (child: any, index: number) => void,
    ): void

    Iterates over children (after flattening & omitting nil).

    Parameters

    • children: Iterable<any, any, any>
    • fn: (child: any, index: number) => void

    Returns void

• last: function

  • last(children: Iterable<any, any, any>): any

    Returns the last non-nil child (after flattening), or undefined.

    Parameters

    • children: Iterable<any, any, any>

    Returns any

  • map(
        children: Iterable<any, any, any>,
        fn: (child: any, index: number) => any,
    ): any[]

    Returns any[]

• only: function

  • only(children: Iterable<any, any, any>): any

    Returns the single child from a children collection (after flattening & omitting nil), or throws if the remaining count is not exactly 1.

    Parameters

    Returns any

• pickOne: function

  • pickOne(
        children: Iterable<any, any, any>,
        predicate: (child: any, index: number) => boolean,
    ): any

    Parameters

    • children: Iterable<any, any, any>
    • predicate: (child: any, index: number) => boolean

    Returns any

• toArray: function

  • toArray(children: Iterable<any, any, any>): any[]

    Converts an iterable children collection into a flat array, omitting null/undefined.

    Parameters
