写一个返回hello world的函数
Example 1:
Input: args = []
Output: "Hello World"
Explanation:
const f = createHelloWorld();
f(); // "Hello World"
The function returned by createHelloWorld should always return "Hello World".
Example 2:
Input: args = [{},null,42]
Output: "Hello World"
Explanation:
const f = createHelloWorld();
f({}, null, 42); // "Hello World"
Any arguments could be passed to the function but it should still always return "Hello World".
Constraints:
0 <= args.length <= 10
solution:
/**
* @return {Function}
*/
var createHelloWorld = function() {
return function(...args) {
return "Hello World"
}
};
/**
* const f = createHelloWorld();
* f(); // "Hello World"
*/
