示例

示例:

const error1 = new TypeError("Error 1");
const error2 = new TypeError("Error 2");
const aggregate = new AggregateError([error1, error2], "Collected errors");
aggregate.errors[0] === error1; // => true
aggregate.errors[1] === error2; // => true

const cause = new TypeError("Something wrong");
const error = new TypeError("Here explained what`s wrong", { cause });
error.cause === cause; // => true

Error.prototype.toString.call({ message: 1, name: 2 }) === "2: 1"; // => true
