    What if i want to remove an element and rearrange the entire array? like
    var x = new Array("lol", "lol2", "lol3", "lol4");
    and I want to remove x[0], so that x becomes ( "lol2", "lol3", "lol4") ?

    @imaverick07 an array starts counting at 0, so if your array is called myarray and has 5 elements, myarray[4] is the last element of that array

    var A = "rapblack2";
    var B = new Array(" doesn't have a high school diplomat"," is a loser");
    alert(A + B[0]);

    @LordShiding I haven't tried it but I don't think you gonna get anything. You may get an output if you use: alert(names + " are all douchebags");

    what is the program you are typing in ??

  25. existenceisrelative Avatar

    Why not just re-order your numbers while adding one?

  26. yomst Avatar

    perhaps, you may just need to hold the existing value into a temporal variable, then append it back to the top array, i.e:


    var temp=names[2]
    names[2]="new person"

    *Correct me if i'm wrong.
