+<p>这里有两种方法创建<code>RegExp</code> 对象: <em>字面量</em> 和 <em>构造函数</em>.</p>
 
 <ul>
- <li><strong>The literal notation's</strong> parameters are enclosed between slashes and do not use quotation marks.</li>
- <li><strong>The constructor function's</strong> parameters are not enclosed between slashes but do use quotation marks.</li>
+ <li><strong>文字符号的</strong> 参数用斜杠括起来，不使用引号。</li>
+ <li><strong>构造函数的</strong> 参数不包含在斜杠之间，但使用引号。</li>
 </ul>
 
-<p>The following three expressions create the same regular expression:</p>
+<p>以下三个表达式创建相同的正则表达式:</p>
 
 <pre class="brush: js notranslate">/ab+c/i
-new RegExp(/ab+c/, 'i') // literal notation
-new RegExp('ab+c', 'i') // constructor
+new RegExp(/ab+c/, 'i') // 字面量
+new RegExp('ab+c', 'i') // 构造函数
 </pre>
 
-<p>The literal notation results in compilation of the regular expression when the expression is evaluated. Use literal notation when the regular expression will remain constant. For example, if you use literal notation to construct a regular expression used in a loop, the regular expression won't be recompiled on each iteration.</p>
+<p>当表达式被求值时，文字表示法会导致对正则表达式的编译。当正则表达式保持不变时，请使用字面量表示法。例如，如果使用字面量表示法来构造循环中使用的正则表达式，则不会在每次迭代时重新编译正则表达式。</p>
 
-<p>The constructor of the regular expression object—for example, <code>new RegExp('ab+c')</code>—results in runtime compilation of the regular expression. Use the constructor function when you know the regular expression pattern will be changing, or you don't know the pattern and are getting it from another source, such as user input.</p>
+<p>正则表达式对象的构造函数—例如，new RegExp('ab+c')—会导致正则表达式的运行时编译。当您知道正则表达式模式将发生变化时，或者您不知道该模式，但正在从其他来源(如用户输入)获取它时，请使用构造函数。</p>
