For example

var htmlCode = "& lt; div & gt; & lt; span & gt; variable with text & lt; / span & gt; + & lt; span & gt; variable with text 2 & lt; / span & gt; & lt; / div & gt; ";
out.insertAdjacentHTML ('afterBegin', htmlCode);

p.s
this is necessary so that later the div can be flexed and these 2 spans can be aligned with the variables

Answer 1

var a = "Hello";
var b = "world";
var htmlCode = `& lt; div & gt; & lt; span & gt; $ {a} & lt; / span & gt; & lt; span & gt; $ {b} & lt; / span & gt; & lt; / div & gt; `;
