# --description--

在上一个挑战中，使用正则表达式`/Hello/`搜索到了字符串`"Hello"`。那个正则表达式在字符串中搜寻`"Hello"`的文字匹配。下面是另一个在字符串中搜寻`"Kevin"`的示例：
|
|
|
|
```js
|
|
let testStr = "Hello, my name is Kevin.";
|
|
let testRegex = /Kevin/;
|
|
testRegex.test(testStr);
|
|
// Returns true
|
|
```
|
|
|
|
任何其他形式的`"Kevin"`都不会被匹配。例如，正则表达式`/Kevin/`不会匹配`"kevin"`或者`"KEVIN"`。
|
|
|
|
```js
|
|
let wrongRegex = /kevin/;
|
|
wrongRegex.test(testStr);
|
|
// Returns false
|
|
```
|
|
|
|
后续的挑战将为你展示如何匹配其他形式的字符串。

|
完成正则表达式`waldoRegex`，在字符串`waldoIsHiding`中匹配到文本`"Waldo"`。
|
|
|
|
# --hints--
|
|
|
|
你的正则表达式`waldoRegex`应该匹配到`'Waldo'`。
|
|
|
|
```js
|
|
assert(waldoRegex.test(waldoIsHiding));
|
|
```
|
|
|
|
你的正则表达式`waldoRegex`不应该搜寻其他的任何内容。
|
|
|
|
```js
|
|
assert(!waldoRegex.test('Somewhere is hiding in this text.'));
|
|
```
|
|
|
|
你应该使用你的正则表达式对字符串执行文字匹配。
|
|
|
|
```js
|
|
assert(!/\/.*\/i/.test(code));
|
|
```
