To make that work for all elements of that class, you could rewrite it as

  document.querySelectorAll('.myclass')
    .forEach(el => el.style.display = 'block')

The jQuery is still shorter, but the vanilla js is definitely manageable.

  Array.from(document.querySelectorAll('.myclass'))
    .forEach(el => el.style.display = 'block')

Though ie11 doesn't have Array.from()

[bonesss]

Hrmmm... maybe someone should make a library that would smooth over browser differences and provide a consistent element selection syntax? Call it JavascriptSelection, or jSelection?

[emergie]

imho 'JavascriptQuery' or 'jQuery' sounds better, oh wait...

[tracker1]

I tend to polyfill older browsers, Array.from is a pretty small one. Sad thing is at a point where it's probably worth it to have 2-3 builds in place... 1 for legacy browsers, one for modern without modules, and one for modules/import/http2 support.

Just haven't taken the time... at least the main app I work on at work doesn't need to support IE11. Latest Edge,, Firefox, Safari and Chrome ... and Chrome is the primary target.

Unfortunately, querySelectorAll returns a NodeList, not an Array. So you cannot use forEach() on it.

NodeList also implements forEach:

[collinmanderson]

It's a very recent addition. IE11 doesn't have it for sure.

[no_gravity]

Not in Edge though.

[hawkice]

The page I linked has a compatibility chart that says Edge 16 has it (no idea if that's a planned release, haven't ever used Edge).

[darepublic]

You can use Array.prototype.forEach.call(nodelist, fn), or Arrays.from(nodelist).forEach

[panzi]

I don't use Windows so I can't test it, but would this work as a polyfill?

    NodeList.prototype.forEach = Array.prototype.forEach;

In Chrome this even returns true:

    NodeList.prototype.forEach === Array.prototype.forEach

[emergie]

Tested in IE11, document.documentMode===11

  Array.prototype.forEach.call(document.querySelectorAll('div'), console.log)

seams to work
