    @kingjs/enumerable.odometer

    Generates arrays of odometer digits.

    Usage

    A typical car odometer has 7 wheels, each wheel has 10 digits, and a new value is generated as the car moves along. These values can be generated for 11 units of distance like this:

    var odometer = require('@kingjs/enumerable.odometer')
    
    var enumerable = odometer([10, 10, 10, 10, 10, 10, 10]);
    var enumerator = enumerable.getEnumerator();
    
    var actual = [];
    for (var distance = 0; distance < 11; distance++) {
      enumerator.moveNext();
      var current = enumerator.current;
      actual.push(current.reverse());
    }
    
    actual;

    result:

    [
      [0, 0, 0, 0, 0, 0, 0],
      [0, 0, 0, 0, 0, 0, 1],
      [0, 0, 0, 0, 0, 0, 2],
      [0, 0, 0, 0, 0, 0, 3],
      [0, 0, 0, 0, 0, 0, 4],
      [0, 0, 0, 0, 0, 0, 5],
      [0, 0, 0, 0, 0, 0, 6],
      [0, 0, 0, 0, 0, 0, 7],
      [0, 0, 0, 0, 0, 0, 8],
      [0, 0, 0, 0, 0, 0, 9],
      [0, 0, 0, 0, 0, 1, 0],
    ];

    API

    function odometer(
      bases?: number[]
    ): Enumerable

    Interfaces

    Parameters

    • bases: an array of normal numbers specifying the number of digits on each wheel of the odometer at each position. May also be passed as an argument list.

    Return Value

    Returns a sequence of arrays composed of the digits produced by an odometer of the specified number of digits and bases. The generator terminates after every combination has been generated.

    Remarks

    A typical odometer increments digits from right to left however odometer increments from left to right so digits increment starting at index 0.
