Is it possible to tell whether a function is in strict mode or not?
<p>My question may sound weird but is there a way to understand whether a function is in strict mode or not by calling from another function?</p>

<pre><code>function a(){
    "use strict";
    // Body
}

function b(){
// Body
}

function isStrict(fn){

    fn.call();
}

isStrict(a); // true
isStrict(b); // false
</code></pre>
