After all the hard work we did to develop Kotlin code, what if we have a very crucial code well written, well tested, but written in JavaScript. Are we going to convert it into Kotlin? No. The way Kotlin code can interoperate with Java, Kotlin for JavaScript is interoperable with JavaScript. This means JavaScript can call Kotlin code and Kotlin can call JavaScript code.
We have covered this as well. Kotlin does not have a Date class that can accept a date in UTC format, but JavaScript has. We will format our dates in JavaScript and Kotlin will call those functions.
We wrote three functions in our index.html file just inside a <script> tag and preceding the Kotlin <script> tags. The sequence does matter here! Consider the following code snippet:
<script>
window.getShortDate = function(longDate) {
var options={month:'long', day:'numeric'};
return new Date(longDate*1000).toLocaleDateString('en-
US',options);...
