How are +variable+ and ${variable} different in javascript?

Question

I'm start coding.

While I was watching a lecture, I saw code like this.

var coworkers = ['go', 'hello', 'hi', 'doit'];
      <script type="text/javascript">
        var i = 0;
        while(i < coworkers.length){
          document.write('<li>'+coworkers[i]+'</li>');
          i = i + 1;
        }

But But when I searched, Said to use ${variable} in JavaScript. and It didn't work.

How are +variable+ and ${variable} different in javascript? Thanks :)

@ProsyArceno Template literal syntax has nothing to do with jQuery — charlietfl, May 11 '21 at 00:12

Those placeholders, like ${variable}, can only be used in template literals, which are always enclosed in backticks(the key right below you escape key).

If it still doesn’t work, maybe you’re using an older browser?
