587d7dab367417b2b2512b6e	Use the every Method to Check that Every Element in an Array Meets a Criteria	1		使用every方法检查数组中的每个元素是否符合条件

Description

every方法都使用数组来检查每个元素是否通过了特定的测试。它返回一个布尔值 - 如果所有值都满足条件，则返回true否则返回false 。例如，以下代码将检查numbers数组中的每个元素是否小于10：

var numbers = [1,5,8,0,10,11];
numbers.every（function（currentValue）{
return currentValue <10;
}）;
//返回false

Instructions

使用checkPositive函数中的every方法检查arr每个元素是否为正数。该函数应返回一个布尔值。

Tests

tests:
  - text: 您的代码应该使用<code>every</code>方法。
    testString: assert(code.match(/\.every/g));
  - text: '<code>checkPositive([1, 2, 3, -4, 5])</code>应该返回<code>false</code> 。'
    testString: assert.isFalse(checkPositive([1, 2, 3, -4, 5]));
  - text: '<code>checkPositive([1, 2, 3, 4, 5])</code>应该返回<code>true</code> 。'
    testString: assert.isTrue(checkPositive([1, 2, 3, 4, 5]));
  - text: '<code>checkPositive([1, -2, 3, -4, 5])</code>应该返回<code>false</code> 。'
    testString: assert.isFalse(checkPositive([1, -2, 3, -4, 5]));

Challenge Seed

function checkPositive(arr) {
  // Add your code below this line
