How change objects color at visu

[buuuudzik]

You've added not appropriate word "and" in condition where in JS you have to use "&&" and there was no ")" at the end of $(function(){});

1. Simple class name withot any other signs.
2. Yes.
3. Every function is in another jQuery wrapper. You can add some comments/title like:
// 1. Coloring value by object________________________________________________

*Use console in browser, and when something strange happen, please console.log(someStrangeVariable)

This is full version in jQuery wrapper:

Code:

$(function(){
 const colorByValue = (obj, type) => {
   const {value} = obj;
   const className = "color-by-value";
   const element = document.querySelector(`.${className}`);
   
        if (!element) return console.log(`You must add custom class "${className}" to some element.`);

   if (value >= 0 && value <= 6) element.style.color = "red";
   else if (value > 6) element.style.color = "green";
   else if (value < 0) element.style.color = "blue";
 };

 grp.listen("1/1/0", colorByValue);
});
