Answer 1

minify javascript is used to compress your javascript code: lets see an example:
this is a normal javascript function

function editField(id){
    //hello hello hello
        var a = 1;
    var b = 2;
    var sum = a + b;

}

when you minify it looks like:

function editField(f){var d=1;var c=2;var e=d+c;};

when you minify the comments and spaces get deleted to improve the performance of your code
