Reset Permission Inheritance of Library using CSOM

Recently I am doing an activity in which I break permission inheritance of library by mistake so I thought, this can easily reset using ribbon option. But the site in which I am working, I am not able to see “Delete Unique Permission” button. So I have executed below code in order to reset permission of library

var siteUrl = <<SiteURL>>

var clientContext = new SP.ClientContext(siteUrl);
this.oList = clientContext.get_web().get_lists().getByTitle(<<ListName>>);
oList.resetRoleInheritance();
clientContext.load(oList);
clientContext.executeQueryAsync(Function.createDelegate(this, this.onQuerySucceeded), Function.createDelegate(this, this.onQueryFailed));

function onQuerySucceeded(sender, args) {
        alert(this.oList.get_title() + ' role inheritance reset');
}


function onQueryFailed(sender, args) {
        alert('Request failed. ' + args.get_message() + '\n' + args.get_stackTrace());
}

You can use same approach for resetting inheritance of folder or document.

Enjoy SharePoint !!!
