Question

我正在使用JSLint来提取以下代码：

'use strict';

var mathService = {
   add: add,
   subtract: subtract,
   multiply: multiply,
   divide: divide,
   power: power,
   squareRoot: squareRoot
};

function add(first, second) {
   return first + second;
}

function subtract(first, second) {
   return first - second;
}

function multiply(first, second) {
   return first * second;
}

function divide(first, second) {
   return first / second;
}

function power(first, second) {
   return Math.pow(first, second);
}

function squareRoot(first) {
   return Math.sqrt(first);
}

当我尝试lint此代码时，我收到对象中每个属性的错误消息，指出它未定义。但是，我不认为必须定义对象属性？在此先感谢您的帮助！

在函数之后移动对象，如

"use strict";

function add(first, second) {
   return first + second;
}

function subtract(first, second) {
   return first - second;
}

function multiply(first, second) {
   return first * second;
}

function divide(first, second) {
   return first / second;
}

function power(first, second) {
   return Math.pow(first, second);
}

function squareRoot(first) {
   return Math.sqrt(first);
}

var mathService = {
   add: add,
   subtract: subtract,
   multiply: multiply,
   divide: divide,
   power: power,
   squareRoot: squareRoot
};

你会得到一些警告，但没有错误。
