I am trying to output the first two objects in the events array using indexOf.

This doesn't return anything:

var whiteList=['css','js'];



var events =[

    {file: 'css/style.css', type:'css'},

    {file: 'js/app.js', type:'js'},

    {file: 'index/html.html', type:'html'}

];



var fileList= events

    .filter(function(event){

    return event.type.indexOf(whiteList) >- 1 

  })



console.log(fileList);

If I change the function like this, it returns the css and js object, although I expected it to return the html object.

var fileList= events

    .filter(function(event){

    return event.type.indexOf('html') 

  })
