First question
Second question

Result : 1. Js array should store every line seperately.

JavaScript has no native way to read files. How you do it depends on your host environment. What is your host environment? Is it a web page? Node.js? Windows Scripting Host? ASP Classic? Something else? — Quentin

Javascript runs on the client and your text file is hosted on the server; Because of that, you need to issue a request to the file, which can be done through AJAX. A first thing would be to request the file, then when you get the response, process it to turn that text response into a javascript array. — Laurent S.

Are you talking about javascript in the browser or are you using node.js to run it on the server? You cannot real files on the server from javascript running in the client. — Niels Abildgaard

       <script type="text/javascript">

            var file_path = "other.txt";
            var output_array = new Array(); // __output array
            var arr = 0;
            var line = "";

            $(document).ready(function(){
                  $.get(file_path, function(data) {
                        for(i = 0; i < data.length; i++){
                            if(data[i] == '\n' || i == ( data.length - 1 )){
                                output_array[arr] = line; arr++; line = "";
                                continue;
                            }
                            line = line + data[i];   
                        } // __creating lines

                        // __testing it
                        for(i = 0; i < output_array.length; i++) alert(output_array[i]);  // __line for testing purpuse

                  }, 'text');
