Javascript/Jquery - Setting default value in function
<p>Using javascript/jquery is there a way to set a variable to a default value if no value is passed in the function? For example</p>

<pre><code>function someFunction(data1,data2)
{


}
</code></pre>

<p>If data1 or data 2 is empty it gives me an undefined value. In php I could do just this:</p>

<pre><code>function somefunction(data1 = '',data2 = '')
{


}
</code></pre>

<p>So if no variable is passed or data1 or data 2 it defaults to ''. In JS/Jquery do I have to check if there is a value and set it accordingly?</p>

<pre><code>function someFunction(data1,data2)
{

if(!data1) {

data1 = '';

}

if(!data2) {

data2 = ''

}

}
</code></pre>

<p>Just seems alot needs to be done to check if variable is empty or not to give it a default value.</p>
