Alert including a string in JS

How can I make an alert in JS that includes text a variable? I have tried this code, but something is wrong.

Code:

---

text1 = "This is a string";
                                alert("This is another string\n" && tekst);

Hi,

its + for strings, and also for integers. Also try using ' instead of "

Code:

---

  text1 = 'This is a string';
  alert('This is another string\n' + text1);
