587d7b7e367417b2b2512b24	Use the Conditional (Ternary) Operator	1		使用条件（三元）运算符

Description

条件运算符（也称为三元运算符）可以用作一行if-else表达式。语法是： condition ? statement-if-true : statement-if-false;以下函数使用if-else语句来检查条件：

function findGreater（a，b）{
if（a> b）{
返回“a更大”;
}
其他{
返回“b更大”;
}
}

这可以使用conditional operator重写：

function findGreater（a，b）{
返回a> b？ “a更大”：“b更大”;
}

Instructions

在checkEqual函数中使用conditional operator来检查两个数字是否相等。该函数应返回true或false。

Tests

tests:
  - text: <code>checkEqual</code>应该使用<code>conditional operator</code>
    testString: assert(/.+?\s*?\?\s*?.+?\s*?:\s*?.+?/.test(code));
  - text: '<code>checkEqual(1, 2)</code>应该返回false'
    testString: assert(checkEqual(1, 2) === "Not Equal");
  - text: '<code>checkEqual(1, 1)</code>应该返回true'
    testString: assert(checkEqual(1, 1) === "Equal");
  - text: '<code>checkEqual(1, -1)</code>应该返回false'
    testString: assert(checkEqual(1, -1) === "Not Equal");

Challenge Seed

function checkEqual(a, b) {

}

checkEqual(1, 2);
