Associativity in javascript

Something Like that:
Associativity

What is Associativity
what order Operator function get called in – left to right or right to left.

For that you need to create first html code.

HTML

<p>Value of a =  <span id="demo1"></span></p>
<p>Value of b =  <span id="demo2"></span></p>
<p>Value of c =  <span id="demo3"></span></p>

After that add this JS code.

JS

var a = 2, b = 3, c = 4;
a = b = c;

document.getElementById("demo1").innerHTML = a;
document.getElementById("demo2").innerHTML = b;
document.getElementById("demo3").innerHTML = c;
