Today I was looking at http://youmightnotneedjquery.com/ and how that could apply to SharePoint UI elements.   Check out the video and code samples below.    Often we need to hide simple page elements and can leverage newer browser JS features for common features like selector and forEach.

Enjoy!

Code – HTML

Code – CSS

/* CSS method */
#ctl00_PlaceHolderSearchArea_SmallSearchInputBox1_csr_sbox {
    display:none;
}
a.ms-core-listMenu-item {
    display: none;
}

Code – JS

// JS approach - http://youmightnotneedjquery.com/
var elements = document.querySelectorAll('a.ms-core-listMenu-item');
Array.prototype.forEach.call(elements, function(el, i){
    el.style.display = 'none';
});
