With the use of shortcodes it is possible to react to the content by emojis. 
So you install the plugin and create new emoji with a title an emoji itself, a count field and an initial count, to fake the initial value of the clicked emoji. 
The shortcake is [emojized id=“8” count=“true”] (or false or empty)
In the new version you can limit votes to one per user.
This plugin demands WP REST API plugin.
It has the same approach as the plugin “Emoji Reactions”

but that seems to be discontinued.

Forget misleading ratings/reactions. Capture accurate data you can actually use when people share the intensity of how they feel about your content.
Providing your readers and users with the best experience and content requires that you get them fully engaged. In order to accomplish that, it is imperative that you accurately capture how they feel about their experiences…in real-time in order to empower you to react, adapt and improve.
We’ve made it easy and seamless for you to do just that! Morphii makes the critical feedback loop more engaging for them by allowing them to simply share their experiences and the intensity of them rather than ask them to try to explain themselves through overly simplistic reaction tools or traditional rating scales.
That key shift in approach minimizes the bias often reflected by existing methods as well as the resulting need to interpret what often is misleading data. The unique interactive methodology Morphii employs has also proven to evoke more responses. That ensures that your outliers will no longer represent the overwhelming majority of your respondents.
The patented means by which a Morphii responder is able to mirror their genuine facial expression confirms that Morphii captures and quantifies like no other image-based tool. The direct result: You are able to make more timely, more informed decisions.
Best of all, the process puts you in control. Simply choose from a library of carefully crafted questions, place them on any webpage and you are on your way to effectively capturing what they are actually feeling and how intensely. With Morphii, you’ll better understand exactly how they feel about your brand, their user experience on your website, their recent purchase…even the content of your blog.
