示例1:
let p4: Promise<any> = d3Fetch.json(url);
p4 = d3Fetch.json(url, init);
let p5: Promise<MyType> = d3Fetch.json<MyType>(url);
p5 = d3Fetch.json<MyType>(url, init);
let myString: Promise<string>;
myString = d3Fetch.text(url);
myString = d3Fetch.text(url, init);
const parseRow = (rawRow: DSVRowString, index: number, columns: string[]): (MyType | undefined | null) => {
const myType: MyType | null = rawRow['foo'] ? { foo: rawRow['foo'] + '+ bar' } : null;
return myType;
};
let promise1: Promise<DSVParsedArray<DSVRowString>>;
