Script Preparation code:
AخA
 
var a = "some text";
var b = "other text";
Tests:

  • plus operator

     
    a + " aaa " + Math.random() + " bbb" + b + " 3210 " + Math.random() + " ccc";

  • concat function

     
    "".concat(a, " aaa ", Math.random(), " bbb ", b, " 3210 ", Math.random(), " ccc");

  • template literals

     
    `${a} aaa ${Math.random()} bbb ${b} 3210 ${Math.random()} ccc`;
