Remove all the DOM elements with a specific tag name in Javascript

How can I remove all the elements with a specific tag name using Javascript. For example, I did the following:

var els = document.getElementsByTagName("center");

and it returned an array of all the center elements. How may I remove all these elements?

Coming from Remove all child elements of a DOM node in JavaScript? and Javascript DOM remove element I know that I can loop through els, find the parent of each element and then remove that specific node. But is there anyother way provided by javascript. Like we can do $('center').remove() in jquery and it removes all the elements with center tag. Anything similar to that in Javascript?
