数组符号的正确JSDoc格式是什么?
Array.<number>
或Array<number>
?
我看过两者可以互换使用,不知道是否有区别。
在Promise<number>
上也可以使用Promise.<number>
吗?

关闭编译器使用Array<number>
。可能其他样式的JSDocs更喜欢Array.<number>
,但我还没有使用它们。
例如:
/**
* Sorts an array of objects by the specified object key and compare
* function. If no compare function is provided, the key values are
* compared in ascending order using <code>goog.array.defaultCompare</code>.
* This won't work for keys that get renamed by the compiler. So use
* {'foo': 1, 'bar': 2} rather than {foo: 1, bar: 2}.
* @param {Array<Object>} arr An array of objects to sort.
* @param {string} key The object key to sort by.
* @param {Function=} opt_compareFn The function to use to compare key
* values.
*/
goog.array.sortObjectsByKey = function(arr, key, opt_compareFn) {
goog.array.sortByKey(arr, function(obj) { return obj[key]; }, opt_compareFn);
};
