<h2 id="Summary" name="Summary">Summary</h2>
<p>The deprecated <code><strong>escape()</strong></code> method computes a new string in which certain characters have been replaced by a hexadecimal escape sequence. Use {{jsxref("Global_Objects/encodeURI", "encodeURI")}} or {{jsxref("Global_Objects/encodeURIComponent", "encodeURIComponent")}} instead.</p>

<h2 id="Description" name="Description">Description</h2>
<p>The <code>escape</code> function is a property of the <em>global object</em>. Special characteres are encoded with the exception of: @*_+-./</p>
<p>The hexadecimal form for characters, whose code unit value is 0xFF or less, is a two-digit escape sequence: %xx. For characters with a greater code unit, the four-digit format %<strong>u</strong>xxxx is used.</p>
<h2>Examples</h2>
<pre class="brush: js">
escape("abc123");     // "abc123"
escape("äöü");        // "%E4%F6%FC"
escape("ć");          // "%u0107"

// special characters
escape("@*_+-./");    // "@*_+-./"</pre>
