Description

  • Title
    Avoid unused variables
  • Description
<p>
When a variable is declared but never used this definitely decreases the readability of the source code and such dead declarations can even be misleading.
</p>

<p>
The following code snippet illustrates this rule :
<p>
<pre>
function fun(a, b) {
  var c = 2;   //Non-Compliant
  return a + b;
}

test(1, 2);
</pre>
