示例1: function

num = d3Array.variance(mixedObjectArray, function (datum, index, array) {
    let d: MixedObject = datum;
    let i: number = index;
    let arr: Array<MixedObject> = array;
    return datum.num;
});

// Test Searching Arrays
// -----------------------------------------------------------------------------

// scan() ----------------------------------------------------------------------

num = d3Array.scan(mixedObjectArray, function (a, b) {
    return a.num - b.num; // a and b are of type MixedObject
});

// bisectLeft() ----------------------------------------------------------------

num = d3Array.bisectLeft([0, 2, 3, 4, 7, 8], 4);
num = d3Array.bisectLeft([0, 2, 3, 4, 7, 8], 4, 1);
num = d3Array.bisectLeft([0, 2, 3, 4, 7, 8], 4, 1, 4);
