如何拼接这种不一致的js命令代码？

var command1 = "console.log('Hello');";
var command2 = "var x = 5;";
var command3 = "console.log(x);";

var concatenatedCode = command1 + command2 + command3;

var commands = [
  "console.log('Hello');",
  "var x = 5;",
  "console.log(x);"
];

var concatenatedCode = commands.join("");

var command1 = "console.log('Hello');";
var command2 = "var x = 5;";
var command3 = "console.log(x);";

var concatenatedCode = `${command1} ${command2} ${command3}`;
