  <h2>Program</h2>
</a>
</div><div><p>Program provides the IDL deserialized client representation of an Anchor
program.</p>
<p>This API is the one stop shop for all things related to communicating with
on-chain programs. Among other things, one can send transactions, fetch
deserialized accounts, decode instruction data, subscribe to account
changes, and listen to events.</p>
<p>In addition to field accessors and methods, the object provides a set of
dynamically generated properties, also known as namespaces, that
map one-to-one to program methods and accounts. These namespaces generally
 can be used as follows:</p>

<a href="#usage" id="usage" style="color: inherit; text-decoration: none;">
  <h2>Usage</h2>
</a>
<pre><code class="language-javascript"><span class="hl-0">program</span><span class="hl-1">.&lt;</span><span class="hl-0">namespace</span><span class="hl-1">&gt;.&lt;</span><span class="hl-0">program</span><span class="hl-1">-</span><span class="hl-0">specific</span><span class="hl-1">-</span><span class="hl-0">method</span><span class="hl-1">&gt;</span>
</code></pre>
<p>API specifics are namespace dependent. The examples used in the documentation
below will refer to the two counter examples found
