List down all the plug-ins installed in your browser

To list down all the plugins installed in your web browser you can use the plugins objects under navigator object in JavaScript. This plugins object is not a JavaScript array, but of type PluginArray and it has the length property and supports iterating it using traditional for loop and using index value to get the values. Hence we cannot use map() or reduce() methods of Array objects. We have to iterate it using for loop and get each plugin using index.

console.log(navigator.plugins);

//PluginArray {0: Plugin, 1: Plugin, 2: Plugin, Chrome PDF Plugin: Plugin, Chrome PDF Viewer: Plugin, Native Client: Plugin, length: 3}

To get total number of plugins installed in the browser:

console.log(navigator.plugins.length); //3

To read name, filename and description:

console.log("Installed Plugins");
console.log("-----------------");
for(var i = 0; i < navigator.plugins.length; i++) {
  console.log("Name - " + navigator.plugins[i].name);
  console.log("File name - " + navigator.plugins[i].filename);
  console.log("Description - " + navigator.plugins[i].description);
  console.log("-----------------");
}
