    js, post new delete old

    how do i get javascript to add to say, 20 lines, and if theres say 3 lines being added, remove the last 3 lines and add the new 3?

    so:

    blah blah
    blah 2
    blah 3
    blah 4

    new line
    blah blah
    blah 2
    blah 3
    blah 4


    blah 4 must be removed.

    thanks

    text.split("\n").slice(2).concat([blah5, blah6, blah7])
