Easy jQuery migration to vanilla JavaScript

jquery_easy_migration.js

// jQuery
$(".review").addClass("hide");

// JavaScript
[].slice.call( document.querySelectorAll(".review") ).filter( function( _e ){
	_e.classList.add("hide");
});

The one issue that everyone has when migrating from JQuery to JavaScript is a replacement for the simple addClass by Class.
Here is some eloquent and performant code that can save you time and effort because you don’t have to write a loop to iterate a node array.

Like this? Clap this:

// JavaScript
document.querySelectorAll(".review").forEach(el => el.classList.add("hide"));

// JavaScript
document.querySelectorAll(".review").forEach(el => el.classList.add("hide"));

This is an ES6 solution, ES5 did not support forEach on a Node List.
