JavaScript USES function to define objects and invoke methods

This article demonstrates how JavaScript USES function to define objects and invoke methods. Share with you for your reference. The specific analysis is as follows:

In JS, you can define objects by function. The following JS code defines an movie function object, and then declares the object by new method, which is also very simple to call.

<script type="text/javascript">
function movie(title, director) {
  this.title = title;
  this.director = director;
  }
var aliens = new movie("Aliens","Cameron");
document.write("aliens:"+aliens.toString());
</script>

The output

aliens:[object Object]

I hope this article is helpful for you to design javascript program.
