How it works.

<div id="profile">
    <img tv-value-src='{{avatar?"default.png"}}'/>
    <span id='firstname'>{{firstname}}</span>
    <span id='lastname'>{{lastname}}</span>
</div>

import {tv} from "./ticoview.js";
const view = tv("#profile")

view.data = {
    firstname: "Kofi",
    lastname: "Manu",
    avatar: "09348534ea87e.png"
}

<div id="profile">
    <img tv-value-src='09348534ea87e.png'/>
    <span id='firstname'>Kofi</span>
    <span id='lastname'>Manu</span>
</div>
