示例1: return
// $ExpectError
mergedArray = d3Array.merge<MixedObject>([[10, 40, 30], [15, 30]]); // fails, type mismatch
// $ExpectError
mergedArray = d3Array.merge([testArray1, [15, 30]]); // fails, type mismatch
mergedArray = d3Array.merge(readonlyTestArrays); // inferred type
mergedArray = d3Array.merge<MixedObject>(readonlyTestArrays); // explicit type
// cross() ---------------------------------------------------------------------
let crossed: Array<[string, number]>;
const chars = ['x', 'y'];
const nums = [1, 2];
crossed = d3Array.cross(chars, nums);
crossed = d3Array.cross<string, number>(chars, nums);
let strArray: string[] = d3Array.cross<number, number, string>([2, 3], [5, 6], (a, b) => (a + b) + 'px');
strArray = d3Array.cross([2, 3], [5, 6], (a, b) => {
const aa: number = a;
const bb: number = b;
return (aa + bb) + 'px';
});
const readonlyChars = chars as ReadonlyArray<string>;
const readonlyNums = new Uint8Array(nums);
crossed = d3Array.cross(readonlyChars, readonlyNums);
crossed = d3Array.cross<string, number>(readonlyChars, readonlyNums);
示例2: MixedObject
new MixedObject(40, new Date(2016, 3, 1)),
new MixedObject(50, new Date(2016, 9, 30)),
]
];
let mergedArray: MixedObject[];
mergedArray = d3Array.merge(testArrays); // inferred type
mergedArray = d3Array.merge<MixedObject>(testArrays); // explicit type
// mergedArray = d3Array.merge<MixedObject>([[10, 40, 30], [15, 30]]); // fails, type mismatch
// cross() ---------------------------------------------------------------------
let crossed: Array<[string, number]>;
crossed = d3Array.cross(['x', 'y'], [1, 2]);
crossed = d3Array.cross<string, number>(['x', 'y'], [1, 2]);
let strArray: string[] = d3Array.cross<number, number, string>([2, 3], [5, 6], (a, b) => (a + b) + 'px');
strArray = d3Array.cross([2, 3], [5, 6], (a, b) => {
let aa: number = a;

// pairs() ---------------------------------------------------------------------
