leetcode 1. 写一个返回hello world的函数

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"
 */
