You're most likely getting <code>NaN</code> as the result of your <code>Date.parse(time)</code> call.
Check the MDN article on <a href="https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Date/parse" rel="nofollow noreferrer">Date.parse</a> for the types of input strings it accepts if you think your time argument should be valid.

You may want to modify your return statement so it's checking for failed parses instead of just undefined, e.g.:

<pre><code>function FormatTime(time, prefix = "") {
 var date = Date.parse(time); // returns NaN if it can't parse
 return Number.isNaN(date) ? "" : prefix + date.toLocaleDateString();
}
</code></pre>

<pre><code> function(ng-model_Name,ng-model_Name) {
 var fromdate = new Date($scope.ng-model_Name.from.toLocaleDateString());
 var todate = new Date($scope.ng-model_Name.to.toLocaleDateString());
 return $scope.variable= asign; 
 }
</code></pre>

Have simple function which returns an error:

<blockquote>
 ERROR: date.toLocaleDateString is not a function
</blockquote>

<pre><code>TypeError: date.toLocaleDateString is not a function
 at FormatTime (../Src/rootdialog.js:87:58)
</code></pre>

Function definition:

<pre><code>function FormatTime(time, prefix = "") {
 var date = Date.parse(time);
 return ((typeof time != "undefined") ? prefix + date.toLocaleDateString() : "");
}
</code></pre>

Function receives <code>Date</code> object as input however even explicit conversion to <code>Date</code> with <code>Date.parse()</code> does not help. Using Node.js 8.x. Any solution?
